University, Nanchang 330063, China Received 13 January 2016; accepted 7 July 2016 Abstract: Rapid solidification of Cu-Co immiscible alloy was investigated by glass-fluxing, spray casting and melt-spinning...: rapid solidification; immiscible alloy; microstructure; nucleation; growth 1 Introduction Rapid solidification belongs to a field of condensed-matter physics and has aroused extensive research......
nanocomposite permanent magnets were prepared under different melt treatment conditions, i.e., the melt temperature was varied prior to ejection onto the quenching wheel. The effect of quenching temperature... uniform microstructure can be obtained directly from the melt quenched at lower temperature. With increasing initial quenching temperature, the optimal quenching speed decreases and the microstructure......
