Abstract

For Cu - 30 at.% Ni droplets processed by containerless solidification under lévitation, the crystallographic texture correlates strongly with the microstructure seen in optical metallography and with the undercooling at which solidification started. The variation in texture is useful in understanding the development of the microstructure, in particular at the extremes of the undercooling range where grain-refined microstructures are observed.
