Growth of Multicomponent Composites from the Melt.
Abstract
An experimental investigation of interface stability during plane front solidification of the two phase alpha plus epsilon region of the Al-Cu-Ni system has been conducted. This has shown that in this region, consistent with those previously examined, interface stability in plane front solidification can be satisfactorily predicted with the aid of a simple constitutional supercooling theory developed in earlier work. Further experimental work has been conducted on the effects of shape and direction variations on both the binary Al-Cu and ternary Al-Cu-Ni eutectic in-situ composites. These are discussed with respect to their influence on the rod on lamellae allignment and consequently the mechanical properties of the composite. Experimental results for the binary Al- Cu system and the ternary Al-Cu-Ni system give good agreement with theory.
