Abstract Aluminum bronze alloy (Cu10%Al4%Fe) was fabricated by equal channel angular extrusion (ECAE) process. The effects of preheating temperature, extrusion numbers and annealing treatment on the surface appearance, microstructure and mechanical properties of the aluminum bronze alloy were investigated. The results show that the appropriate preheating temperature is 650 °C. When the ECAE pass number increases from 1 to 4, the hardness, yield strength and the plastic properties increase gradually. The alloy has the best mechanical properties after 60 min’s annealing treatment at 500 °C.
