Abstract
A commercial aluminum bronze alloy (Cu―15%Al―4%Fe) produced by hot-rolling was subjected to equal channel angular extrusion (ECAE) process at high temperature. The effect of ECAE on microstructure, mechanical and tribological properties of the alloy was investigated. Experimental results showed that grain size decreased and the second phase was rearranged after ECAE. The hardness and strength of the alloy with ECAE were higher than that of the alloy without ECAE and increased with the increase pass number. The wear resistance of the alloy after ECAE was significantly improved.
