A MODEL FOR BAINITIC TRANSFORMATION KINETICS WITHPARABOLIC NUCLEATION RATE Z.Liu1,K.F.Yao1,C.C.Liu1 (1.Department of Mechanical Engineering, Tsinghua University, Beijing 100084, China) Abstract:Based on the assumptions of parabolic variation of nucleation rate versus time andtransformation kinetics depending mainly on nucleation rate, a different model forbainitic transformation kinetics......
NUCLEATION BEHAVIOR OF Al8Fe4Nd PHASE IN RAPIDLY SOLIDIFIED AI-Fe-V-Si-Nd ALLOY H.Pang1,M.G.Zeng3,J.N.Deng3,Z.H.Jin1 (1.S henyang National Laboratory for Material Science, Institute of Metal...). The phase selection of thealloy during solidification and the nucleation behavior of Al8Fe4Nd phase were ana-lyzed witinin the framework of time-dependent nucleation theory. The incubation timefor......
