Textures and Mechanical Properties of Melt-Extruded Al-Cu Alloys

Abstract

The influence of heat treatment on mechanical properties and textures of a meltextruded Al-4.5wt.%Cu alloy bar was studied. And its characteristics are compared with those of a hot-extruded Al-Cu alloy bar. The results show that the mechanical properties of the melt-extruded Al-Cu alloy bar were slightly higher than those of the hot-extruded bar, and the difference in their mechanical properties was narrowed after the T6 treatment. The recrystallization texture was found in the melt-extruded Al-Cu alloy bar, and the fiber texture of the hot-extruded Al-Cu alloy bar was found different from that of the melt-extruded Al-Cu alloy bar.
