Comparison of dendrite and dispersive structure in rapidly solidified Cu-Co immiscible alloy with different heat flow modes被引量：3
《Transactions of Nonferrous Metals Society of China》2017年第1期227-233,共7页李圣 刘峰 杨伟 
Project(SKLSP201118)supported by the State Key Laboratory of Solidification Processing in Northwestern Polytechnical University,China;Projects(51431008,51461032)supported by the National Natural Science Foundation of China;Project(51125002)supported by the China National Natural Science Foundation for Distinguished Young Scholars;Project(GJJ14504)supported by the Education Department of Jiangxi Province,China
Rapid solidification of Cu-Co immiscible alloy was investigated by glass-fluxing, spray casting and melt-spinning techniques. Both the transition from dendrite to dispersive structure and corresponding scale evolution...
