Abstract

In this paper

an Al-Fe alloy chemical composition has been designed; semi-solid forming technology has been used to prepare the alloy. The microstructure of the alloy as cast

electromagnetic stirred and semi-solid formation state has been analyzed and the mechanical properties of the alloy have been tested. The results show that microstructure of the alloy becomes obviously thinner after the alloying and electromagnetic stirring

semi-solid formation processing makes the microstructure further refined. The length and thickness of the second phase decrease; at the same time

the acute angles disappear

and their distributions also become more homogeneous. The tensile strength of the alloy increases about 79.7% compared with the alloy at cast condition.
