| 1 | Microstructural Evolution and Mechanical Behaviour of Metastable Cu-Zr-Co Alloys显示文摘Three different CueZreCo alloys, namely Cu40Zr37.5Co22.5, Cu42.5Zr45Co12.5and Cu49Zr49Co2, were obtained by rapid cooling. The microstructure and phase formation of as-cast rods with diameters of 2 mm are compared with those of the respective ingots. An increasing Co content stabilises the B2 CuZr phase and leads to the precipitation of a ternary CueZreCo phase. The variation of the cooling rate affects the size of the B2 dendrites as well as the volume fraction and the morphology of the interdendritic phases. The mechanical properties were determined in compression and all alloys show a certain plastic deformability despite the presence of several binary and ternary intermetallic phases. The deformation mechanisms are discussed on the basis of the microstructures and the constituent phases. | S.Pauly K.Kosiba P.Gargarella B.Escher K.K.Song G.Wang U.Kühn J.Eckert | 2014 | Journal of Materials Science & Technology2014，30，6： | 8 |
| 2 | Plastic deformation of a Zr-based bulk metallic glass fabricated by selective laser melting显示文摘Fully amorphous Zr_(52.5)Cu_(17.9)Ni_(14.6)Al_(10)Ti_(5) bulk metallic glass(BMG) samples with a relative density exceeding 98% were fabricated via selective laser melting(SLM).High fracture stresses of around1700 MPa and a reproducible plastic strain of about 0.5% were obtained for cylindrical SLM samples.The analysis of the observed serrations during compressive loading implies that the shear-band dynamics in the additively manufactured samples distinctly differ from those of the as-cast glass.This phenomenon appears to originate from the presence of uniformly dispersed spherical pores as well as from the more pronounced heterogeneity of the glass itself as revealed by instrumented indentation.Despite these heterogeneities,the shear bands are straight and form in the plane of maximum shear stress.Additive manufacturing,hence,might not only allow for producing large BMG samples with complex geometries but also for manipulating their deformation behaviour through tailoring porosity and structural heterogeneity. | L.Deng K.Kosiba R.Limbach L.Wondraczek U.Kühn S.Pauly | 2021 | Journal of Materials Science & Technology2021，，1： | 2 |

| 14 | A NEW METHOD FOR THE PREPARATION OF PHENOLS AND ITS DERIVATIVES显示文摘a-Oxo ketene dithioacetals 2 via 1,2-nucleophilie addition by methallyl magnesius chloride afforded corresponding alcohols (3). Treated with water or methanol and catalyzed by Lewis acid, the alcohols 3 were converted regiospecifical ly to substituted phenols 5’ or related phenol methyl ethers 5 respectively. This reaction is a novel approach to the synthesis of phenols and their derivatives starting from non-aromatic precursors. | Qun LIU~* Department of Chemistry, Northeast Normal University, Changchun, 130024.Kocienski PHILIP Department of Chemistry, The University of Southampton, Southampton.S09 5.NH,U.K | 1991 | Chinese Chemical Letters1991，2，5： | 1 |

| 19 | 临床实验中高效液相色谱法的样品制备技术显示文摘在临床实验室中,样品的制备技术,是成功的应用高效液相色谱法(HPLC)的一项具有决定性意义的组成部分。临床样品的直接注射,在限定的病例中虽是允许的,但通常情况下都需先进行样品的制备。理想的样品制备方法,是在除去干扰物的同时,能使待分析物得到选择性的分离。这样,既可提高分析的速度、灵敏度与准确度,也能延长分析柱的使用寿命。样品制备的方法临床样品通常为血液(全血、红细胞、白细胞、淋巴细胞、血清或血浆)和尿液。不过脑脊髓液(CSF)、羊水、胆汁、粪便与组织的活检,也都可用来进行分析。至于选择何种样品制备方法,须视样品的来源、 | C.K.Lim Harrow U.K 李德斌 | 1990 | 国外医学(临床生物化学与检验学分册)1990，11，2： | 0 |
