Fracture Characteristics of the Cr-V Ledeburitic Steel Vanadis 6
Original language description
The P/M Vanadis 6 cold work steel was selected for the investigation. The specimens for the three point bending tests and fracture toughness test were austenitized at different temperatures, quenched with or without the sub-zero period and subsequently double tempered. It was found that the bending strength decreased with increased austenitizing temperature and also with the use of sub-zero treatment. The average fracture toughness decreased with increased austenitizing temperature, too, but it increased with the sub-zero treatment. The lowering of bending strength can be considered as natural because of the austenitic grain growth, as well as increased portion of martensite in the case of sub-zero processed samples. In the case of fracture toughness,the situation seems to be more complex. On the one side, the relationship fracture toughness vs. austenitizing temperature behaves in an expected way - the KIC decreases as the austenitizing temperature increases.
