摘要:
Applying glass fluxing combined with cyclic superheating and rapid quenching after recalescence, the solidification of undercooled immiscible Fe-Cu alloy melts was studied. Subjected to low undercooling, a coarse dendritic pattern results, where both Cu precipitation and dot substructure can be observed. For sufficiently high undercooling, a typical granular structure forms, where the dot substructure still exists because of the effect of post-recalescence. Only if both sufficiently high underco ...More
