Abstract

This paper presents the effect of temperature and aging time on the microstructure and mechanical properties of CuAl9Fe4 alloy. When changing the aging temperature from 250 to 550^oC and the aging time from 01 hour to 03 hours, the maximum hardness value reaches 99.5HRB after aging at 350^oC for 02 hours and the mass loss reaches 0.1239g. This result is similar to the result of design of experiments (DoE). After aging at 350^oC for 2 hours, the microstructure of the alloy includes of matrix is solid solution - α phase; fine γ2 and Fe3Al phases disperse in the α matrix - α phase.
