摘要
通过对4032铝合金Φ200 mm棒材的热挤压和热处理工业实验,对挤压工艺进行了优化,并研究了热处理制度对其力学性能的影响。研究结果表明,4032铝合金最佳的挤压温度区间为380～430℃;最佳挤压速度为0.1～0.2 m.min-1。经510℃固溶30 min,160℃时效1.5 h后,挤压棒材具有最佳的综合力学性能,其屈服强度达344 MPa,抗拉强度达382 MPa,延伸率达6.25%。
The extrusion process of 4032 aluminum alloy was optimized and the effect of heat-treatment process on the mechanical properties of 4032 aluminum alloy bar also was studied,according to the hot-extrusion and heat-treatment industrial examination of Φ 200 mm 4032 aluminum alloy bar.The results showed that the best extrusion temperature range was from 380 to 430 ℃ and the best extrusion ratio was 0.1～0.2 m · min-1 of 4032 aluminum alloy.After being solid solution at 510 ℃ for 30 min and artificial aging at 160 ℃ for 1.5 h,the extrusion bar showed the best synthesis mechanical properties.The yield strength,tensile strength and elongation ratio of the alloy was 344,382 MPa and 6.25% respectively.
