摘要：
40 mm thick coarse-grained (up to 10 - 20 mm) CuCrZr mold wall to 2 mm thick pure copper plate lap joint was performed using friction stir welding (FSW) operating a H13 die steel tool. The obtained defect-free joint indicates the potential of FSW to restore worn-out copper molds wall. FSW resulted in ultrafine microstructure (0.5 -1.0 mu m) of stir zone strengthened by chromium and Cu5Zr nanoparticles. Grain boundary and dispersion hardening increase the hardness of the stir zone up to 150 -190 HV1 compared to 110 -130 HV1 of the initial coarse-grained structure. Based on the results, friction stir welding and related friction stir processing technologies are proposed as a severe plastic deformation method to obtain an ultrafine-grained state of CuCrZr alloys.
