Abstract
Some of the tungsten and vanadium was replaced by titanium in the high speed steel M7 to achieve good casting properties. The microstructure and other characteristics of as cast and heat treated specimens of this experimental steel were investigated by means of optical and electron microscopy with the aid of energy dispersive X-ray (EDX) analysis. Several heat cycle routines were studied to determine the best mechanical properties. These properties have been compared with those of standard M7 and M2 high speed steels to reach a better understanding of the behaviour of the cast experimental steel.
