The properties of the metallic matrix are fundamental to obtain high wear resistance. The example shown in Fig. 1 refers to cast irons tested as grinding balls in a ball mill [2].Because of different heat treatments one sample has high hardness martensitic matrix while the other presents a low hardness austenitic matrix.
