Abstract

Joint effect of chromium and titanium on structure and properties of hard castings is investigated in present work. It is determined that titanium neutralizes carbide-forming effect of chromium in the investigated concentration intervals. In the presence of titanium, the effect of chromium on hardness of samples is lower as compared to its individual effect. Therefore, addition of only chromium raised hardness of experiment billets by 2.1 times; together with titanium (0.2%) only by 1.1 times, and at 0.01% Ti increase of chromium content did not affect the hardness.
