Effect of Heat Treatment on Proportion of Duplex Fiber Texture of Aluminium Magnesium Silicon Alloy

Abstract

In the present study, an attempt has been made to understand the texture evolution of Aluminium alloy 6082-T6 after different aging heat treatment process. Effects of heat treatment in controlling the variation and domination of one fiber texture over the other in a duplex fiber texture have been observed. Texture studies were carried out with ND direction parallel to direction of extrusion. Solutionised and aged samples have shown the variations in volume fraction of <100> and <111> fibre due to effect of re-crystallization and precipitation. The presence of clusters of solutes and β′′ precipitates alters the proportion of volume fraction of <100> and <111> duplex fibers. Peak aged samples showed significant strengthening of <100> fiber as compared to solutionised and aged samples.

“…Face-centered cubic metals and their alloys have fiber textures that are, particularly, sensitive to many variables. Textures usually observed are duplex fiber <111>//ND + <100>//ND, with the volume fraction of grains assigned to each of these directions varying greatly according to the material composition, as well as its previous deformation and heat treatment [8,9].…”
