Research on Synthesis of High-Strength Aluminum Alloys. Part II. Control of Grain Structure During Hot Working.
Abstract
The effects of deformation parameters on the tendency of 2024 aluminum alloy to recrystallize either during hot working or during subsequent solution heat treatment were examined. Samples were upset under controlled conditions in the Gleeble programmed thermal-mechanical test machine. The behavior of homogenized 2024 was compared with that of a high purity Al-4.6Cu alloy and with cast 2024 and 2124. Based on the Gleeble results, hot rolling procedures were designed for producing a fine equiaxed grain structure in sheet rolled from either homogenized 2024 or cast 2124. A limited quantity of sheet was rolled according to these procedures and evaluated to determine tensile and fatigue properties. (Author)
