摘要
The structure and properties of diamond tools with steel powder matrices are studied. It is shown that the physical-mechanical and performance characteristics of the metallic matrices depend on the volume of the deformation phase transformation of austenite to martensite. The tools are tested under industrial conditions for cutting of various rocks. The optimal composition of the matrix is selected, possessing the highest volume of the phase transformation in cutting of all of the tested rocks.
