Abstract

Abstract:

The microstructure and tensile strength of 7N01 aluminum alloy extruded profiles under T5 heat treatment were studied. The results show that the microstructure of the 7N01 profile has a certain degree of non-uniformity and anisotropy, and the grains in the extrusion direction are elongated to form a deformation texture. Such deformation texture can more effectively resist plastic deformation in the extrusion direction, so the strength in the extrusion direction is higher than that perpendicular to the extrusion direction, and the elongation is reduced by about 2%. The tensile strength and yield strength of the 7N01 aluminum alloy extruded profiles at room temperature is about 368 MPa and about 318 MPa respectively, and the comprehensive properties is good.

Key words: 7N01 aluminum alloy profile, mechanical properties, microstructure, deformation texture, anisotropy
