Effect of sub-zero treatment on mechanical properties of vanadis 6 PM ledeburitic tool steel
Original language description
The P/M Vanadis 6 cold work steel was austenitized, quenched and tempered. For selected sets of specimens, also sub-zero period was inserted between quenching and tempering. The structure, hardness and three point bending strength was investigated as a function parameters of heat treatment. The as-quenched hardness of the material raises with the use of the sub-zero period. On the other side, the use of sub-zero period results in a slight hardness decrease of the as-tempered material. Furthermore it wasfound that the three point bending strength decreased markedly with increased austenitizing temperature and also slightly with the use of sub-zero treatment. The lowering of bending strength with increasing austenitizing temperature can be considered asnatural because of the austenitic grain growth. On the other hand, the lowering of bending strength due to the use of sub-zero processing can not be explained as simply as expected on first sight.
