摘要
The change in the structure of welds made with a new welding wire and subjected to high-velocity impact was investigated by optical and scanning electron microscopy and X-ray diffraction analysis. It is shown that after welding, a structure consisting of martensite, delta-ferrite, and metastable austenite is formed in the weld metal. The subsequent severe impact leads to hardening of the weld metal due to the transformation of metastable austenite to strain-induced martensite. Kinetic microindentation of the weld was performed.
