Abstract

This work presents results of microstructural development through solidification, heat treated processes and characterization of two low-alloyed hypereutectoid alloys, emphasizing the effects of the alloy chemical composition. Samples of different compositions were prepared by melting in the induction furnace. The microstructural difference of the different HSS steels will affect the performance of the end products. The main features of the as cast microstructure are the distribution and morphology of eutectic carbides which have been obtained through progress in alloy design concerning the type, morphology, and the volume fraction of the eutectic carbides. Samples were characterized by optical and Scanning electron microscopy.
