摘要
导电铝合金以其质量轻,导电性能好,成本低等优点,成为了目前导电材料领域的研究热点之一。本文制备了新型Al-0.5Zr-0.2RE-0.2B合金,讨论了热处理工艺参数对其力学性能的影响规律。研究表明:随固溶温度、固溶时间、时效温度、时效时间的增加,合金的强度都随之增加,并达到一个最大值。随后,随这些工艺参数的增加,材料性能反而降低。由此,得到了合金的最佳热处理工艺为在440℃固溶12小时,水淬后在205℃时效16小时。本文的研究为导电铝合金的应用提供了数据支持。
Conductive aluminum alloys have become one of the research hotspots in the area of conductive materials because of its light weight,good conductivity and low cost.In this paper,we prepared Al-0.5Zr-0.2RE-0.2B alloy,and studied the effect of heat-treatment processing parameters on me-chanical properties of the alloys.The results indicated that the strength of the alloys increased with the increase of solution temperature,solution time,aged temperature and aged time,and it reached the highest value quickly.Then the strength decreased with improvement of those pa-rameters above on the contrary.At last,solution at 440?C for 12 h,and aged at 205?C for 16 h was gained as optimal hear-treatment processing.Data in this research will provide support for appli-cation of electrical aluminum alloys.
