Abstract

Abstract: The types, dimensions and quantities of inclusions have been examined to quantitatively investigate their influence on the bending strength and impact toughness of HIPed high-speed steel. MgSiO3 inclusion was found to be less harmful than Al2 O3 inclusion in terms of mechanical properties. Additionally, the inclusion of Al2 O3 of 0-20 μm under 0.02 vol.% showed a slight influence on the bending strength of certain HSS.
