热处理对SiCp/6061Al基复合材料等离子弧焊接头性能的影响

Effect of heat treatment on plasma arc welded joint of SiCp/6061Al MMCs

    摘要
  • 摘要: 热处理对SiCp/6061Al基复合材料等离子弧原位焊接接头组织与性能的影响较为明显,固溶处理+时效与退火相比,前者对接头的改善作用更佳。经500℃固溶处理2h+12h时效热处理后,接头组织得到良好的改善,细长的Al3Ti相变为短小棒状,消除了晶间偏析,组织更加均匀;热影响区组织中晶粒均得到比较明显的细化,比较接近母材晶粒的大小,焊接接头强度较未热处理时有了较大提高,达到245MPa。

     

    Abstract: Heat treatment has much obvious effect on microstructure and properties of joint in plasma arc "in-situ" welding of SiCp/6061Al MMCs.Prior to annealing process, the improvement effect of solution treatment and aging on microstructures and properties of the joint of SiCp/6061Al MMCs is better.Massive bulky phases Al3Ti turn into short rod-like, and intergranular segregation is eliminated, and more homogeneous particles are obtained;heat affected zone is refined, and strength of the joint was improved to 245 MPa.
