Microstructures and mechanical properties after spheroidizing annealing (SA) of GCr15 bearing steel with without an alternating magnetic field (AMF) were investigated. It was found that the application AMF at austenitizing stage promoted dissolution carbides, accelerated process increased hardness quenched sample. After isothermal annealing, carbides in sample more uniformly distributed became ...

We prepare multi-component transition monocarbides of chosen composition by arc-melting together a pre-alloy the metals and cast iron. Based on elements Ti, Ta, V, Nb W, 51 different binary, ternary quaternary compositions are produced. The intrinsic hardness H modulus E resulting iron-embedded carbide particles directly measured using nanoindentation. Of all tested here WC shows highest while ...
