Heat treatment changes the structure of the cobalt binder phase and the properties of the WC-Co hardmetals. The higher the cobalt content in the alloy is, the more effective the heat treatment is. The present work has found that the transformation of α-Co to ε-Co can be depressed by quenching the specimens in oil from 1000℃ and hence the transverse rupture strength of these specimens can be increased. During tempering the quenched specimens, new precipitated phases which have dispersion hardening effect on the cobalt binder phase have been observed

Using sand moulds for step-shape casting tests and different silicon percentage of nodular cast iron it was possible to separate structural variations produced during freezing from those occurring at Ac1 transformation temperature. The results show that an increase in silicon content leading to different variation in the matrix structure> leads to a changing mechanical properties of nodular cast irons. Tensile strength and elongation of obtained as-cast nodular cast iron with the composition of 3.9%C, 3.2%Si, 0.5%Mn are maximum of about 524.5N/mm2 and 19.8% accordingly. In the same nodular cast iron, but only with 0.1% Mn the silicon addition first increases after decreases elongation, impact toughness and hardness. But tensile strength changes to the opposite side
