Phase selection of ternary intermetallic compounds during solidification of high zinc magnesium alloy GUAN Shao-kang(关绍康)1, ZHANG Chun-xiang(张春香)1, WANG Li-guo(王利国)1, WU Li-hong(吴立鸿)1, CHEN Pei...; Abstract: The phase selection of ternary intermetallic compound τ phase (Mg32(Al, Zn)49 ) and φ phase (Al2Mg5Zn2) in high zinc magnesium alloys was studied......
ternary system at 1 023 K. AgZr2 and AgTi2 form a continuous solid solution, namely Ag(Ti,Zr)2. Four three-phase regions: AgTi +AgZr + Ag, AgTi +AgZr + Ag (Ti, Zr)2, α-Zr +β(Ti, Zr) + Ag (Ti, Zr) 2 and α-Ti +β(Ti, Zr) + Ag (Ti, Zr)2 exist in the isothermal section. No ternary compound is observed. Key words: Ag-Ti-Zr; phase diagram; diffusion triple; isothermal section 1 Introduction ......
and mechanical properties of refractory high entropy alloys, NbMoTiVSi0.2 alloys with different La contents were prepared. Phase constitution, microstructure evolution, compressive properties and related... on the phase constitution, microstructure evolution, mechanical properties and the related mechanisms were thoroughly studied. 2 Experimental The raw materials were sponge titanium (purity ≥99.98......
. In the present work, attention is given to the phase constitution and microstructure of secondary phases in the as-cast and heat-treated Mg-Nd-Zn alloy. Considering the effects of Zn element, in order..., the existing eutectic compounds are Mg-Nd-Zn ternary phases: T phases and W phases. After the heat treatment, with increasing the temperature or time, it was found that T phase almost dissolved into the α-Mg......
FORMATION OF MANGANESE SILICIDE THIN FILMS BY SOLID PHASE REACTION E.Q.Xie1,W.W.Wang1,D.Y.He1,N.Jiang1 (1.Department of Physics,Lanzhou University,Lanzhou 730000,China) Abstract:Manganese silicide MnSi2-x thin films have been prepared on n-type silicon substratesthrough solid phase reaction. The heterostructures were analyzed by X-ray diffraction,Rutherford backscattering spectroscopy, Fourier......
