| 4 | MICROSTRUCTURE EVALUATION OF SEMI-SOLID STEEL MATERIALS IN ROLLING PROCESS AND THE RESULTING MECHANICAL PROPERTIES显示文摘The experimental study on the familiar 60Si2Mn and lCrl8Ni9Ti materials rolled in the semi-solid state was carried out. Experimental results show that the segregation of liquid occurs when the semi-solid slurry is rolled, which influences the microstructure and mechanics performance of workpiece under room temperature. The globular solid particles don’t present plastic deformation unless high solid fraction. At the same time, the mechanics property of workpiece is pretty good while the semi-solid slurry of 1Cr18Ni9Ti material is rolled by a pass and no other treatment. | R.B. Song, Y.L. Kang, J.L.

| 5 | 俄罗斯在国际能源战略格局变化中的地位及中俄能源合作显示文摘2014年6月后,国际油价大幅下跌,由每桶100多美元跌至50多美元,最低甚至跌破每桶30美元。2017年下半年以来,国际油价不断攀升,2018年1月26日美国西得克萨斯原油期货价格收于每桶65.53美元,布伦特原油期货价格收于每桶70.38美元,创下近三年国际油价的新高。市场人士普遍认为,此轮国际油价的回升与俄罗斯同沙特阿拉伯等欧佩克国家和非欧佩克产油国订立的减产协议有关。众所周知,国际油价的形成受多种因素影响,石油的供给与需求、世界经济的景气状况、美元指数走势、投资基金行为和地缘政治等都对国际油价产生影响。俄罗斯作为世界重要产油国,在'页岩革命'和国际能源格局不断变化的情况下,其在国际石油供给中处于何种地位?在国际油价形成中具有怎样的话语权?主要石油生产国之间将存在怎样的合作与博弈?此轮回升是否意味着低油价时代暂时告一段落?本刊编辑部特邀请国内外专家对上述问题进行讨论,并对中国未来能源安全战略及中俄能源合作的前景进行分析。 | 冯玉军 庞昌伟 许勤华 B.A.马特维耶夫 农雪梅 孙永祥 王永中 刘旭 周延丽 A.M.别洛戈里耶夫 高晓慧 徐洪峰 富景筠 徐斌 刘乾 王晓光 | 2018 | 欧亚经济2018，，3： | 17 |
| 6 | TiZr-base Bulk Metallic Glass with over 50 mm in Diameter显示文摘Low-cost TiZr-base bulk metallic glasses(BMGs)(Ti36.1Zr33.2Ni5.8Be24.9)100-xCux(x=5,7 and 9) with a maximum size of over 50 mm in diameter were developed by optimizing the alloy composition.The idea is initiated by selecting a particular microstructure comprising primary β-Ti dendrite and amorphous phase.Afterwards,based on this composition of amorphous phase,a class of TiZr-base bulk metallic glasses was designed step by step to reach the optimum composition range.The glass transition temperature(Tg),initial crystallization temperature(Tx) and width of supercooled region(△T) of(Ti36.1Zr33.2Ni5.8Be24.9)91Cu9 BMG are 611,655 and 44 K,respectively.The(Ti36.1Zr33.2Ni5.8Be24.9)91Cu9 BMG exhibits low density of 5.541 g·cm-3 and high compressive fracture strength of 1800 MPa,which promises the potential application as structural materials. | M.

| 7 | THE APPARENT VISCOSITY OF SEMI-SOLID AZ91D ALLOY AT STEADY STATE显示文摘The Rheological behavior of semi-solid AZ91D at steady state is studied using a Couettetype viscometer in the present paper. The results show that the apparent viscosity ofsemi-solid AZ91D at the steady state increases with the solid fraction increasing, andgoes up sharply when the solid fraction reaches a certain value, which is called criticalfraction. In addition, the apparent viscosity of semi-solid AZ91D at the steady statetakes on a distinct downtrend with the shearing rate increasing, which indicates astrong shear thinning property. In addition, the critical solid fraction becomes higherunder larger shearing rate, owing to the more globular shape of the solid particles.Based on the present experiment results, an empirical equation is built as that, relatingthe steady state apparent viscosity of semi-solid AZ91D with the solid fraction fs andshearing rate γ at the same time: ηapp=10. 74exp(6.95fs)γ-0.86. | Z.S.

| 8 | State of the Art on Micromilling of Materials,a Review显示文摘The trend towards miniaturization has increased dramatically over the last decade, especially within the fields concerned with bioengineering, microelectronics, and aerospace. Micromilling is among the principal manufacturing processes which have allowed the development of components possessing micrometric dimensions, being used to the manufacture of both forming tools and the final product. The aim of this work is to present the principal aspects related to this technology, with emphasis on the work material requirements, tool materials and geometry, cutting forces and temperature, quality of the finished product, process modelling and monitoring and machine tool requirements. It can be noticed that size effect possesses a relevant role with regard to the selection of both work material (grain size) and tooling (edge radius). Low forces and temperature are recorded during micromilling, however, the specific cutting force may reach high values because of the ploughing effect observed as the uncut chip thickness is reduced. Finally, burr formation is the principal concern with regard to the quality of the finished part. | M.A.Cmara J.C. Campos Rubio A.M. Abro J.P.

| 13 | PREPARATION STUDY OF SEMI-SOLID 60Si2Mn SPRING STEEL SLURRY显示文摘The nondendritic semi-solid slurry preparation of 60Si2Mn spring steel is studied in this paper. The experiments show that when stirred for 2 minutes under the test condition, the semi-solid slurry with 50%-60% fraction solid phase and spherical primary austenite in the size of 100-300μm can be obtained and is easy to be discharged from the little bottom hole of the stirring chamber. The more homogeneous temperature field and solute distribution of the 60Si2Mn spring steel melt appear because of the electromagnetic stirring, which restrains the formation of large primary austenitic dendrites and create a base to form spheroidized structure. The stronger temperature fluctuation in the melt with many rosette primary austenites caused by stirring and the remelting of the secondary arm roots in the same time are the most important reasons for deposition of spheroidized primary austenites. | W.M.

| 14 | Characterization and separation of pyrite from Abu Tartur black shale显示文摘This work aimed for pyrite separation from Abu Tartur black shale as a source of sulfur to be an added economic value of Abu Tartur area. The considered samples in the present work were collected from a core drilled in Abu Tartur plateau representing the pyrite-rich black shale of the U. Cretaceous age.Sample characterization was carried out using petrographic microscope, XRD, DTA/DTG, C/S and XRF techniques. Clay minerals, silt-sized quartz, calcite, and hematite were the main minerals associating pyrite(5.34%). Liberation behavior of the sample was about 80% below 5 lm.Sample processing was achieved through one-day soaking followed by classification using 1 inch Mozley hydro-cyclone where about 35.5% by weight went to underflow and 64.5% went to overflow.The underflow product was subjected to an advanced gravity separation process using SB-40 Falcon Concentrator through a CCD statistical design prepared by Design-Expert 6.0 software proposed to optimize the separation process through a study for the effects of frequency(Hz) and water pressure(Psi) on both assay and recovery of the sulfur-rich heavy fraction.A heavy concentrate weighed 10.90% with inorganic sulfur content reached 11.37%(21.24% pyrite) with overall recovery(50.01%) was obtained after two cleaning at the optimum conditions. | Ibrahim S.S.

| 15 | Effect of Electroplating Parameters on Microstructure of Nanocrystalline Nickel Coatings显示文摘In order to achieve the optimum conditions for electroplating nanocrystalline nickel coating from Watts-type bath, the effect of some process parameters namely, bath temperature, current density, and saccharin addition on grain size and texture coefficient (TC= I(200)/I(111)) of the deposits were investigated by X-ray diffraction (XRD). The results showed that in a bath containing 5 g/L saccharin, by increasing the bath temperature from 45°C to 55°C, the grain size decreased, whereas further increase of bath temperature resulted in a contrary effect. By increasing the current density from 10 to 75 mA/cm2, both the grain size and TC decreased, while further increase in current density had no significant effect on the grain size. At a given current density, the grain size and TC decreased rapidly by increasing the saccharin content before leveling off at 3 g/L of saccharin. Finally, based on the grain refining the optimum conditions for producing nanocrystalline nickel coating from Watts-type bath have been proposed. | A.M. Rashidi A.

| 16 | Use and application of CFC-11,CFC-12,CFC-113 and SF6 as environmental tracers of groundwater residence time:A review显示文摘Groundwater residence time is a fundamental property of groundwater to understand important hydrogeological issues,such as deriving sustainable abstraction volumes,or,the evolution of groundwater quality.The anthropogenic trace gases chlorofluorocarbons (CFC-11,CFC-12 and CFC-113) and sulphur hexafluoride (SF6) are ideal in this regard because they have been released globally at known rates and become dissolved in groundwater following Henry’s Law,integrating over large spatial (global) and temporal (decades) scales.The CFCs and SF6 are able to date groundwater up to w100 years old with the caveat of certain simplifying assumptions.However,the inversion of environmental tracer concentrations (CFCs and SF6) to derive groundwater age rests on the accurate determination of groundwater recharge parameters,namely temperature,elevation,salinity and excess air,in addition to resolving the potential for contamination,degradation and unsaturated zone effects.This review explores the fundamentals of CFC-11,CFC-12,CFC-113 and SF6 as environmental tracers of groundwater age and recommends complementary techniques throughout.Once this relatively simple and inexpensive technique has been used to determine initial concentrations at the recharge zone,setting the groundwater dating ‘clock’ to zero,this review then explores the meaning of groundwater ‘age’ in relation to measured environmental tracer concentrations.It is shown that the CFCs and SF6 may be applied to a wide-range of hydrogeological problems and suggests that environmental tracers are particularly powerful tools when integrated with numerical flow and transport models. | L.A.

| 17 | 对乙酰氨基酚引起的急性肝衰竭:一项美国多中心前瞻性研究结果显示文摘Severe acetaminophen hepatotoxicity frequently leads to acute liver failure (ALF). We determined the incidence, risk factors, and outcomes of acetaminophen- induced ALF at 22 tertiary care centers in the United States. Detailed prospective data were gathered on 662 consecutive patients over a 6- year period fulfilling standard criteria for ALF (coagulopathy and encephalopathy), from which 275 (42% )were determined to result from acetaminophen liver injury. The annual percentage of acetaminophen-related ALF rose during the study from 28% in 1998 to 51% in 2003. Median dose ingested was 24 g (equivalent to 48 extra-strength tablets). Unintentional overdoses accounted for 131 (48% ) cases, intentional (suicide attempts) 122 (44% ), and 22 (8% ) were of unknown intent. In the unintentional group, 38% took two or more acetaminophen preparations simultaneously, and 63% used narcotic-containing compounds. Eighty-one percent of unintentional patients reported taking acetaminophen and/or other analgesics for acute or chronic pain syndromes. Overall, 178 subjects (65% ) survived, 74 (27% ) died without transplantation, and 23 subjects (8% ) underwent liver transplantation; 71% were alive at 3 weeks. Transplant free survival rate and rate of liver transplantation were similar between intentional and unintentional groups. In conclusion, acetaminophen hepatotoxicity far exceeds other causes of acute liver failure in the United States. Susceptible patients have concomitant depression, chronic pain, alcohol or narcotic use, and/or take several preparations simultaneously. Education of patients, physicians, and pharmacies to limit high-risk use settings is recommended. | Larson A.M. Polson J. Fontana R.J. 宋平 | 2006 | 世界核心医学期刊文摘(胃肠病学分册)2006，2，8： | 5 |
| 18 | 胺的种类、pH和矿粒粒度对石英浮选的影响显示文摘对于分选铁英岩铁矿石以生产球团矿给料来说,阳离子反浮选石英是一种最重要的方法。选矿工作者在着手解决这一工艺过程时,常面临着下述两个难题:1)粗粒的石英不能很好地与胺类捕收剂发生反应;2)细粒的氧化铁颗粒不能很好地被胶凝化的玉米淀粉所抑制。本文探讨了解决第一个难题的一些措施。在常规的机械搅拌式浮选机中进行实验室规模的试验,以研究在三种pH值和四种不同用量的醚单胺和醚二胺捕收剂的条件下,不同粒度范围石英的浮选性能。可以看出,在浮选中等粒度和粗粒的石英时,醚二胺捕收剂更为有效,而在浮选细粒的石英时则是醚单胺的捕收效果更好。并且还发现,浮选矿浆中有一定数量的细粒石英的存在能提高中等粒度和粗粒的石英的浮选效果。 | A.M.维艾拉 张兴仁 木子 | 2007 | 国外金属矿选矿2007，44，12： | 5 |
