Abstract
The results of studying the microstructure and microhardness of ring lugs on discs made of a steel–copper pseudoalloy after laser thermal treatment using a fiber laser with a power of 1 kW are given. It is revealed that the partial melting region in which melting occurs in the volumes of the low-melting component (copper) in the initial structure and contacting segments of steel matrix is formed in the material in addition to the total melting zone. Then the quenching zone from the solid state follows, in which the maximal hardness up to 1000 HV is attained for best samples in the volume of martensite, which is formed in perlite colonies of the initial steel–copper material.
