Abstract
This study was carried out to investigate the effects of alloying elements and vertical centrifugal casting(V.C.C.) conditions on microstructural behavior and mechanical properties, including hardness and wear characteristics in high speed steel. The hardness and wear test were used to evaluate the mechanical property of high speed steel manufactured by both gravity casting and V.C.C. With the increase in V element addition, the hardness increased. It was found that the amount of MC carbide was increased and M_7C₃ carbide were decreased with the increase in V and Nb content, The cell and carbides became finer and the amount of M_7C₃ carbide was decreased, according to the increase in revolution speed due to increase cooling rate.
