چکیده انگلیسی
A study of diffusion wear mechanism in 1.2344 X40CrMoV5-1 steel FSW tool has been carried out from the standpoint of tribological layer generation and interaction with the tool׳s metal. It was shown that during FSW of AMg5M aluminum alloy the latter covers the tool׳s working surface and then iron/aluminum reaction diffusion is initiated under the conditions of high mechanical stress and temperature. Since diffusion by the former austenite grain boundaries is much faster than that of by volume an intermetallic compound is formed inside the tool׳s metal thus causing embrittlement and pulling out the tool׳s metal fragments.
