Semi-Solid Processing of Powder Steels in Cryogenically-Cooled Die

Popis výsledku v původním jazyce

By processing of steels in semi-solid state it is possible to achieve untypical structures also with commonly used steels. It can be demonstrated on the tool steel X210Cr12. After the semi-solid state processing, 96% of the structure can be created by metastable austenite. In the structure there are polyedric grains stored in a ledeburitic network. A combination of semi-solid state processing and rapid solidification represents a new method to achieve more significant modifications of a structure. Due to an intensive suppression of diffusive transformations and creating of supersaturated metastable structures, it is possible to achieve a very fine carbidic network or very fine precipitates. During the experiment two tool steels CPM 15V and CPM S30V were processed by an unconventional method. Since the steels are made by powder metallurgy, their initial structure is created by globular carbides stored in a ferritic matrix. Both materials have a high fracture of alloying elements, especi
