2原子发射光谱法在钢铁工业上的最新研究进展:定量分析与非金属夹杂物分析的结合显示文摘尽管原子发射光谱法(OES)是钢铁工业中近几十年来应用最广的一种分析技术,但其在C,N,O分析领域和夹杂物分析潜能方面的重大发展使它再次受到广泛关注。各钢铁公司都在努力提高生产力,控制成本和改善产品质量。而原子发射光谱法的最新发展恰好能帮助钢铁生产商们实现这些目标。电源控制光源(CCS)和时间分辩光谱仪(TRS)两项技术的结合使原子发射光谱法达到了最好效能。由于这些技术的采用和内标的恰当选择,大部分元素的分析都得到了改善。所有钢成分中的重要元素现在都可以按照钢铁生产商的大部分需求进行分析。尤其是C和N成分较低时,与传统方法例如燃烧分析法相比,OES可以降低成本,提高生产力。火花数据采集处理系统(Spark-DAT,单火花分析发射光谱)使OES的应用范围更广,因为它可以最快的速度分析出钢铁中的非金属夹杂物。因此,非常有利于炼钢过程中的杂质监测和工艺控制,金属材料中夹杂物的快速过滤或者高成本技术的替代,以改善由某些类型夹杂物的存在和数量决定的钢的特性或成分。本文将重点介绍钢铁定量分析和夹杂物分析在分析方法和实际应用上的进展。BOHLEN J-M YELLEPEDDI Ravi 2009冶金分析2009,29,10:4
3Alloying effect of silver in magnesium on the development of microstructure and mechanical properties by indirect extrusion显示文摘The effect of Ag in solid solution on the microstructure,texture and the deformation behaviour of indirectly extruded Mg was investigated.Ag as a solid solution strengthener affects the behaviour during extrusion,resulting in enhanced deformation related heating and corresponding coarser grained microstructures.No substantial effect on the texture development is revealed.The mechanical properties simultaneously increase in stress and strain levels with increasing Ag content,especially in tension as a result of the changing impact of the slip modes which can be associated with a decrease of the lattice parameters as well as the c/a ratio of the hcp lattice structure.In compression tests with twin dominated flow,the impact is much smaller on the compressive yield stress but higher with respect to the twinning related strain hardening rate.Solid solution strength functions for Fleischer and Labusch were determined,also confirming the anisotropic behaviour of the extruded Mg alloys.Bjorn Wiese Regine Willumeit-Römer Dietmar Letzig Jan Bohlen 2021Journal of Magnesium and Alloys2021,9,1:3

5Deteriorated corrosion performance of micro-alloyed Mg-Zn alloy after heat treatment and mechanical processing显示文摘The corrosion performances of the as-cast and solution-treated Mg-0.5Zn samples were investigated in 0.9%Na Cl solution and compared.From the electrochemical measurement results and corrosion morphology observations,it is found that the corrosion resistance of Mg-0.5Zn deteriorated with the extension of solution treatment duration.The main reason was the formation of Fe-Si precipitates with higher Fe concentrations during heat treatment.The Fe-Si precipitates,especially the ones with high Fe contents influenced the corrosion initiation and propagation significantly.In regard of corrosion performance,the solution-treated and then extruded sample was also performing not as good as the cast and then directly extruded sample.Yiming Jin Carsten Blawert Hong Yang Bjorn Wiese Jan Bohlen Di Mei Min Deng Frank Feyerabend Regine Willumeit 2021Journal of Materials Science & Technology2021,,33:3
6Corrosion performance,corrosion fatigue behavior and mechanical integrity of an extruded Mg4Zn0.2Sn alloy显示文摘Magnesium alloys are promising as load bearing components.They are inevitably exposed to cyclic loading and corrosive environment in actual service,which can consequently result in corrosion fatigue failure and loss of mechanical integrity of the material.Therefore,in the present study,the corrosion behavior,corrosion fatigue performance and mechanical integrity of an extruded Mg4Zn0.2Sn(wt.%)alloy were thoroughly studied in two corrosive electrolytes.Strong localized corrosion occurred when the alloy was immersed in deionized water based sodium chloride(NaCl)solution.The poor corrosion resistance of the alloy resulted in a fast deterioration of the tensile properties after pre-exposure to salt spray and a poor fatigue resistance in deionized water based NaCl solution.In comparison,the active dissolution of the substrate was sufficiently suppressed in artificial tap water based NaCl solution due to the formation of highly protective corrosion product layers.This consequently conferred longer fatigue life on the alloy in the electrolyte.Our results emphasized the influence of corrosion on the fatigue behavior and tensile properties of magnesium alloys.Pingli Jiang Carsten Blawert Jan Bohlen Mikhail L.Zheludkevich 2020Journal of Materials Science & Technology2020,59,24:3
