摘要/Abstract

摘要： 研究了T6热处理对高压压铸的ADC12铝合金组织和力学性能的影响。结果表明,经过510 ℃×1 h固溶处理和200 ℃×6 h人工时效后,ADC12铝合金压铸件的微观组织由细小的共晶组织和α固溶体组成,细小的共晶组织是高压压铸过程中形成的。热处理后,铝合金中共晶Si相和Al₂Cu相主要以近似球状的颗粒物存在;铝合金压铸件经过T6热处理后,过渡相从基体相上完全脱溶,形成稳定的θ相和平衡的α固溶体。经过510 ℃×1 h固溶处理和200 ℃×6 h人工时效后,ADC12铝合金压铸件达到最大硬度128 HBW。这是析出强化相Al₂Cu使得过饱和固溶体具有特殊晶体结构导致的。

Abstract: Effect of T6 heat treatment on microstructure and mechanical properties of high pressure die cast ADC12 aluminum alloy was studied. The results show that after solution treatment at 510 ℃ for 1 h and artificial aging at 200 ℃ for 6 h, the microstructure of the ADC12 aluminum alloy die casting is composed of fine eutectic structure and α solid solution, where the fine eutectic structure is formed during the high pressure die casting process. After heat treatment, eutectic Si phase and Al₂Cu phase in the aluminum alloy mainly exist as approximately spherical particles. After T6 heat treatment, the transition phase of the aluminum alloy die casting completely precipitates from the matrix phase, forming a stable θ phase and an α solid solution. After solution treatment at 510 ℃ for 1 h and artificial aging at 200 ℃ for 6 h, the hardness of the ADC12 aluminum alloy die casting reaches the maximum, being 128 HBW, this is caused by the precipitation strengthening phase Al₂Cu, which makes the supersaturated solid solution has a special crystal structure.
