Abstract
Ferrite (Fea - alpha irons with cubic body-centrred lattice) is either a free metaliographical or a bound one as a main component of manifold casting materials. The ferrite hardening by alloying and strengthening processes ieads to the so-called "Consolidation Process" which is important in the filed of usage hardness casting alloys, especially. The paper reported here refers to different sort of materials to which the ferrite consolidation took place by nitrogen microalloying and by boron - titanium modification, as follows: • Grey cast iron for machine tools (working machines); • High chromium white cast iron both for balls and armours of crushing ball mills; • Hypereutectoid steels (ADAMFT type) for rollers.
