About Abnormal Grain Growth in Joints Obtained by Friction Stir Welding

  • WELDED JOINTS
  • Published:
Metal Science and Heat Treatment Aims and scope

Some special features of abnormal grain growth in welded joints of aluminum alloys formed by fiction stir welding (FSW) are studied. The microstructure and the texture of the alloys are determined after welding and annealing at 400, 450 and 500°C for different times. The abnormal grain growth is shown to depend much on the macroscopic inhomogeneity of the structure inside the weld.

Notes

  1. We present the international names of the alloys because we have studied metals of foreign producers.

  2. It should be noted that the studied alloy also contained dispersoids of phase Al3Cr2Mg3. Since the volume fraction of this phase was very low, its action of the growth of grains was presumed to be low and was not allowed for in the simulation.
