摘　　要：切取工业生产条件下生产的6082铝合金13.0 mm厚度的热轧板材试样在盐浴炉内加热至(525±2)℃保温60m in,水中淬火。然后进行人工时效,研究人工时效前停放不同时间、人工时效过程保温不同时间等工艺参数对6082-T651铝合金板材力学性能和显微组织的影响。结果表明,在工业生产条件下6082-T651铝合金板材人工时效前最佳停放时间为不超过4 h,人工时效的保温时间以12 h～20 h为宜。The samples have been taken from hot rolled 6082 aluminum alloy plate with thickness of 13.0 mm produced at production condition.The samples have been heated in the salt bath to（525± 2）℃ with 60 min holding and then quenched in water.The influence of keeping time before aging and holding time during aging on mechanical properties and microstructure of 6082-T651 aluminum alloy hot rolled plate has been investigated.To produce high quality 6082-T651 aluminum alloy plate the optimum keeping time before aging is 4 h and no more,the suitable holding time during aging is 12 h to 20 h.
