Texture and mechanical property anisotropy in an Al-Mg-Si-Cu alloy

This work describes the correlation of microstructure-texture and texture-m echanical properties of a hot rolled Al-Mg-Si-Cu alloy in T-6 condition. Te xture measurement was carried out on both the surfaces and mid thickness le vels of the specimen using conventional pole figure as well as orientation distribution function (ODF) methods. Tensile properties and fracture toughn ess of the alloys were evaluated at different orientations with respect to the rolling directions. High cycle fatigue properties were evaluated in the rolling direction. From these observations, the in plane anisotropy factor (%IPA), K-IQ values and fatigue life were calculated and correlated with t extures and microstructures/fracture features of the alloy.
