CRYSTALLIZATION OF AMORPHOUS Fe82Si4B14 ALLOY UNDER HIGH PRESSURE

Abstract
High pressure effect on the crystallization processes of amorphous Fe82Si4B14 alloy were investigated and the T-T-T diagram at lbar and 77kbar were obtained. Results indicated that the pressure derivative of crystallization temperature of this amorphous alloy changes with the change of annealing duration during which the crystallization take place. Bcc-Fe(Si) solid solution crystalize preferentially at normal pressure while at high pressure DOe type Fe3B and bcc-Fe(Si) will form simultaneously.
