Homogenization for 3105 aluminium alloy ingots

doi:10.13251/j.issn.0254-6051.2024.08.035

Abstract

Abstract: Different homogenization processes were applied to 3105 aluminum alloy ingots, and microstructure, conductivity and hardness were tested. The results show that the precipitation of solute atoms and the redissolution of compounds occur simultaneously in the 3105 aluminum alloy during the homogenization process. The optimum homogenization process is 630 ℃×9 h. Under this process, the alloy has the lowest conductivity (22 MS/m), as well as a relatively high solid solubility, which is conducive to the subsequent product performance enhancement. The hardness is also the lowest (36.94 HV5), which can better satisfy the demand of low deformation resistance for extrusion hot working.

Key words: 3105 aluminium alloy ingot, homogenization, conductivity, hardness
