热处理工艺对多元Al-Si合金力学性能的影响
Effect of Heat Treatment on Mechanical Properties of Multi-Component Al-Si Alloy
摘要
Abstract
In order to study the influence of heat treatments on the comprehensive mechanical properties of multiple Al-Si alloy, the alloy specimens in the state of as-cast, water quenching+aging treatment and aging treatment, were carried out in testing machine of 3 000 kN, the microstructures of the alloy were analyzed by the optical microscope and SEM, then the mechanical properties were tested. The results show that, the mechanical property of the multi-component Al-Si alloy treated by as-cast water quenching+aging is the best among the three states, and then the aging treatment, the mechanical property of as-cast is the worst. For as-cast water quenching is equivalent to a transient solution treatment, dispersed phases (Al2Cu% Mg2Si and 0' phases etc.) would integrate into a solid solution in the solution treatment, then separated out in the aging treatment, which drastically improved the mechanical properties of the alloy.关键词
