It is shown that explosive welding may be used to create bimetal material exhibiting simultaneously high strength and good damping capacity. Bimetal strength is provided due to a layer of high-strength high-quality steel 30KhGSA, and damping capacity is provided as a result of using a layer of damping steel 60G40D. A heat treatment regime is revealed with which bimetal damping capacity surpasses that of alloy 60G40D as a result of forming a tetragonal distorted lattice and twinned structure of manganese-copper alloy.
