Modification of Metastable Microstructure of CPM15V Steel by Heat Exposure after Treatment in Semi-Solid State

Original language description

Processing in the semi-solid state allows the benefits of the process of forming and casting to be combined. In addition to obtaining complicated shapes, unusual forms of structures with exceptional properties can also be formed. A special processing procedure in the semi-solid state for very small parts has been developed, which is called mini-thixoforming, is able to handle CPM15V steel powder. From the original ferrite matrix with primary chromium - vanadium carbides - a mixed structure was obtainedby processing consisting of metastable austenite, rod-shaped chromium - vanadium carbides and the original chromium - vanadium carbides. Compared to the initial state (micro hardness approx. HV10 330), this structure achieved, as a result of the relatively high rate of cooling in the form, a hardness of approx. 730 HV10. Due to the fact that this is a metastable structure, experimental heating to temperatures 400, 500, 600, 700, 800 ° C for 1 hour was performed. With exposure at temperat
