“…[7][8][9][10] Therefore, increased wear resistance is an important reason for the development of a new Cr-Mo-V cast hot-working die steel. [11][12][13] Wang et al and Cui et al studied the effects of alloying elements, [14,15] rare-earth modification, [16] and second carbides [17,18] on the elevated-temperature wear of this cast steel. Wei et al [19] studied the wear behavior of the cast steel at 673 K (400°C) and discovered that the cast steel had a substantially higher wear resistance than H13 and H21 steels.…”

The wear behavior and mechanisms of a Cr-Mo-V cast hot-working die steel with three microstructures (tempered martensite, troostite, and sorbite) were studied systematically through the dry-sliding wear tests within a normal load range of 50 to 300 N and an ambient temperature range of 298 K to 673 K (25°C to 400°C) by a pin-on-disk high-temperature wear machine. Five different mechanisms were observed in the experiments, namely adhesive, abrasive, mild oxidative, oxidative, and extrusive wear; one or more of those mechanisms would be dominant within particular ranges of load and temperature. The transition of wear mechanisms depended on the formation of tribo-oxides, which was related closely to load and temperature, and their delamination, which was mainly influenced by the matrix. By increasing the load and ambient temperature, the protective effect of tribo-oxides first strengthened, then decreased, and in some cases disappeared. Under a load ranging 50 to 300 N at 298 K (25°C) and a load of 50 N at 473 K (200°C), adhesive wear was the dominant wear mechanism, and abrasive wear appeared simultaneously. The wear was of mild oxidative type under a load ranging 100 to 300 N at 473 K (200°C) and a load ranging 50 to 150 N at 673 K (400°C) for tempered martensite and tempered troostite as well as under a load of 100 N at 473 K (200°C) and a load ranging 50 to 100 N at 673 K (400°C) for tempered sorbite. At the load of 200 N or greater, or the temperatures above 673 K (400°C), oxidative wear (beyond mild oxidative wear) prevailed. When the highest load of 300 N at 673 K (400°C) was applied, extrusive wear started to dominate for the tempered sorbite.

“…Recently a new group of PM steels was developed that features 10-20 vol.% NbC in a stainless martensitic matrix. This leads to superior corrosion resistance compared to the above-mentioned stainless tool steels (Huth et al 2009a;. The fabrication of the new materials is, however, complicated and they are not yet commercially available.…”

The effect of different homogenization parameters on the microstructure and element distribution of Cr8Mo2SiV cold-work die steel ingot is investigated. Based on the Thermo-Calc software and laser confocal microscopy, the optimal heat treatment temperature range from 1160 to 1230 C is obtained for experimental steel. In order to improve dendritic segregation of as-cast microstructure consisting of a large number of network eutectic carbides enriched in alloying elements, the homogenization treatment is carried out at the above determined temperatures for 0.5, 1, and 3 h, respectively. Then, according to the segregation ratio of Cr element, the homogenization at 1180 C for 3 h successfully eliminates the microsegregation, which is in agreement with the calculation of the diffusion kinetic model of Cr element.
