摘要

The wear of the tool made of a ZhS6U heat-resistant nickel alloy during friction stir welding of a high-strength titanium alloy is analyzed. A metallographic analysis of the formed joints reveals the traces of intermetallic compounds of titanium and nickel. An X‑ray phase analysis confirms their presence both in the formed permanent joints and on the tool surface. A visual analysis of the tools and their measurements after welding show that the tool pins have experienced the most severe wear.
