Study on Rare Earth-Containing Phases in TiAl Based Alloys Prepared by Non-Equilibrium Solidification Processing 沈军1,贾均1,马学著1 (1.School of Material Science and Engineering, Harbin Institute of Technology) Abstract:Microstructure evolution of rare earth rich phase of rapidly-solidified (RS) TiAl based alloys was investigated. The two rapid-solidification techniques employed are melt-spinning......
, Nanchang 330063, China) Abstract: Non-equilibrium solidified specimens of AZ91D magnesium alloy were fabricated by copper mould casting and melt-spinning techniques, separately. The corresponding... be fabricated by melt-spinning method. Both the distribution of Mg and Al elements in rapid solidified alloy are homogeneous without the occurrence of solute segregation. Key words: magnesium alloy; non......
