Preparation of Bimetal with Good Damping Properties

Resumo

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.
