Solidification pathway and phase transformation behavior in a beta-solidified gamma-TiAl based alloyH.Xu1,2,X.B.Li1,W.W.Xing1,L.Shu1,Y.C.Ma1,K.Liu11. Institute of Metal Research,Chinese Academy of Sciences摘 要:The phase transformation behavior of an as-cast Ti-42Al-5 Mn(at.%) alloy after subsequent quenching from 1380 ℃ to 1000 ℃ was investigated based......
MICRO-DESCRIPTION OF THE SOLUTE-FIELD AND THE PHASE-FIELD MODEL FOR ISOTHERMAL PHASE TRANSITION IN BINARY ALLOYS R.X.Liu1,H.M.Ding1,L.L.Chen1 (1.Research Studio of Solidification Simulation, College of Materials Science and Engineering,Huazhong University of Science and Technology, Wuhan 430074, China) Abstract:A new phase field method for two-dimensional simulations of binary alloy......

microstructure stability, but the m phase is precipitated in the superalloy with 6% W during aging. The strip-like m phase is precipitated to be parallel or perpendicular to each other along the <..., but the creep lifetime of alloy is obviously decreased with the increase of the element W content up to 6%. The fact that the m phase is precipitated in the superalloy with 6% W during applied stress......
, there is very limited understanding on the microstructural evolution in the aging process for Cu-Ni-Mn alloys. A new phase is precipitated in the grains and at the grain boundaries [2] when Cu-Ni-Mn alloy... 2014; accepted 23 January 2015 Abstract: The microstructure evolution and phase transformation of Cu-20Ni-20Mn (mass fraction, %) alloy at 450 °C were investigated by X-ray diffraction and transmission......

took place as the soft magnetic phases were crystallized, and then the hard magnetic Nd2Fe14B was precipitated from them. While α-Fe and a metastable 1:7 (TbCu7-type) phase were formed simultaneously...Phase Formation and Magnetic Properties of Nanocomposite Nd-Fe-B Adjusted by Small Amount of Dy and Co M B Kim1,T S Jang1,D H Lee1,H S Aum2,T W Lim1 (1.Division of Materials and Chemical......
