materials, the intermetallic compound GdPd was synthesized by arc melting and heat treatment. The microstructure, magnetic and magnetocaloric properties of the intermetallic compound of GdPd were investigated...Magnetic properties and large magnetocaloric effects of GdPd intermetallic compoundJianjun Huo1,Yusong Du1,2,Gang Cheng1,2,Xiaofei Wu1,2,Lei Ma1,2,Jiang Wang1,2,Zhengcai Xia3,4,Guanghui Rao1,21......
by directional solidification, and its microstructure and tensile properties at elevated temperatures were investigated. Microstructure observations reveal that the γ′ precipitates are arrayed in the γ matrix... Conclusions 1) The superalloy with high content of refractory elements is fabricated by directional solidification. Microstructure observations show that besides the γ′ precipitates and γ matrix, some......

Microstructure Evolution of a Ternary Monotectic Alloy During Directional SolidificationShu Chen,Jiu-Zhou Zhao,Hong-Xiang Jiang,Jie HeInstitute of Metal Research,Chinese Academy of Sciences摘 要:A model was developed to describe the microstracture evolution in a directionally solidified ternary monotectic alloy.The directional solidification experiments......
in fatigue is possibly associated with the microstructure of AZ80. A homogeneous single phase structure probably alleviates the directional anisotropy of fatigue properties of the wrought magnesium... that solid solution treatment or reducing the size of intermetallic compound may improve fatigue strength of magnesium alloys[8-10]. Hence, we conclude that the homogeneous single phase structure of AZ80......
