Abstract

Loading of bimetallic moulds, having as basic material VCrW85, loaded by welding through various procedures, is realized with view of obtaining an adequate resistance to heat and at the same time maintaining a hardness over 55 HRC la 873-923 K. Therefore we have to choose the optimum variant (variants) of loading for achieving the desired mechanic characteristics and an as uniform as possible dispersion of the carbides of W within the steel microstructure frame.
