CRYSTALLIZATION AND HARDNESS CHANGE OF RAPIDLY SOLIDIFIED Fe-C-Si-Mo ALLOYS

Crystallization behavior of rapidly solidified Fe-C-Si-Mo alloy ribbons made by single rol- ler method together with their changes in phase and hardness have been studied by X-ray diffraction and SEM.The results show that the alloys attribute their very high Vickers hardness to numerous fine carbides formed during crystallization.
