Vacuum Electromagnetic Levitation Melting and Undercooling of Peritectic Terfenol-D 马伟增1,季诚昌1,郑红星1,李建国1 (1.School of Materials Science and Engineering, Shanghai Jiaotong University, Shanghai 200030, China) Abstract:For the first time, the undercooling of a magnetostrictive material-a near peritectic Tb0.27Dy0.73Fe1.90 alloy was realized by vacuum electromagnetic levitation melting and 60 K......
for the lower and larger undercooling, and plastic deformation and fracture for the medium undercooling. Key words: Ni-Pb monotectic alloy; high undercooling; wear rate; wear mechanism CLC number: TG115.5... alloys[7-9]. Single phase, eutectic and peritectic melts have been studied systematically by high undercooling and rapid solidification, and can solidify at a higher speed under larger undercooling......

Key words: Ni-Pb hypermonotectic alloy; monotectic cell; high undercooling; liquid-liquid phase separation; water-quenched microstructure... be fully inhibited and a homogeneous structure can be acquired[9]. It hence gives us an important edification whether the homogeneous hypermonotectic alloy can be prepared by high undercooling......

Nucleation and growth of high purity aluminum grains in directional solidification bulk sample without electromagnetic stirring ZHANG Jiao(张 佼)1, 2, SHU Da(疏 达)1, RAO Qun-li(饶群力)3... solidification device was used to fabricate d 80 mm high purity aluminum ingots. SEM and AFM were used to detect the shape of grain boundaries. The orientation of the grain was studied by X-ray......
