Název v původním jazyce

Development of microstructure from powder tool steel obtained through semi-solid metal working

Popis výsledku v původním jazyce

Semi-solid metal working (SSM) joins advantages of precision casting and hot forging. The technology allows to obtain a product with a complicated shape in one forming step. Homogenous microstructure is an advantage to the comparison with die casting. The SSM method could be also used for difficult machinable and formable materials. The aim of this research was to invert the conventional microstructure configuration and to obtain hard particles in tough matrix. Tool steel with trade mark CPM 15V was chosen for the experiment. The steel is produced through using powder metallurgy and contains high content of carbon, vanadium and chromium. The content of alloying elements is more than 20 weight per cent. The initial microstructure of the steel is composed of ferrite matrix with chromium and vanadium carbides. The experimental material was heated up to the semi-solid state when liquid phase was approximately 30% and deformed. Metallographic analysis, chemical microanalyses and X-Ray phase
