Effects of Ru on the microstructure and phase stability of a single crystal superalloyZhen-xue Shi, Jia-rong Li, and Shi-zhong Liu Science and Technology on Advanced High Temperature Structural... and phase stability of the single crystal superalloy were investigated. γ′ directional coarsening and rafting were observed in the Ru-free alloy and Ru-containing alloy after long-term aging at 1070?C......
; Phase composition, transition and structure stability of functionally graded cemented carbide with dual phase structure ZHANG Li(张 立)1, CHEN Shu(陈 述)2, XIONG Xiang-jun(熊湘君)1, HE Yue-hui(贺跃辉)1, HUANG Bai-yun(黄伯云)1, ZHANG Chuan-fu(张传福)3 (1. State Key Laboratory of Powder......
. The hardness and elastic modulus of the main precipitated phases were also analyzed and compared with those of the α-Mg matrix on the basis of nanoindentation tests. The results show that the RS alloy consists of either a petal-like icosahedral quasicrystal(IQC) phase(~20 μm) and block-shaped H1 phase(~15 μm) or IQC particles with an average grain size of ~107 nm as well as a small proportion of amorphous......
Phase Chemistry of the Complexes of RE Amino Acids 高胜利1,李焕勇1,陈三平1,史启祯1 (1.Department of Chemistry, Shaanxi Key Laboratory of Physico-Inorganic Chemistry, Northwest University, Xi′an 710069, China) Abstract:Forty-three phase diagrams of ternary system concerning rare earth salts, α-amino acids and water, which were constructed by phase equilibrium methods, were expounded. The influences......
Overcoming the strength-ductility trade-off by tailoring grain-boundary metastable Si-containing phase in β-type titanium alloyX.Luo1,L.H.Liu1,C.Yang1,H.Z.Lu1,H.W.Ma1,Z.Wang1,D.D.Li2,L.C.Zhang3,Y... shell-shaped metastable S1 phase surrounding the columnar β-Ti grain was intercepted successfully via nonequilibrium rapid solidification achieved by selective laser melting(SLM).Subsequently,the thin......
dissolved, but some cuboid-shaped RE-rich phase precipitated. As the temperature increased, the morphology of the Mg5(GdEr) phase was transformed into the same morphology as that at 460 °C for 6 h... that the continuous network-like Mg5(GdY) phase decomposed into fragmentized phase and some cuboid-shaped compounds with a composition of Mg2Y3Gd2 precipitated after solution solid treatment. It is suggested......
Effect of Deformation on Order-Disorder Phase Transformation in Cu-Zn Alloy Xu Liang1,Liu Jianhua1,Zhang Ruijun2 (1.College of Physical Science and Technology, Heilongjiang University, Harbin 150080, China;2.State Key laboratory of Metastable Materials Science and Technology, Yan Shan University, Qinhuangdao 066004, China) Abstract:The phase transformation temperature of ordered β......
Partial phase diagram of Au-Ag-Dy ternary system ZHANG Kang-hou(张康侯), CHEN Jiang(陈 江) (Kunming Institute of Precious Metals, Kunming 650221, China) Abstract: On the basis of Au-Ag, Au-Dy and Ag-Dy binary phase diagrams, the 700℃ isothermal section of Au-Ag-Dy ternary system(Dy≤35%, mole fraction) was established by X-ray diffraction analysis, differential thermal analysis and optical......
