words: Cu-Cr alloy; liquid phase separation; melt spinning; rapid cooling 1 Introduction Cu-Cr alloys containing 20%-50%Cr have been widely investigated because they are the most important... not widely used. In order to obtain refined microstructures, in our prior work[10] we prepared Cu-Cr ribbons containing 3%-25%Cr by melt spinning. It was found that a lot of larger Cr particles were......
