Fe-Ti合金のメカニカルアロイングによる合成 Synthesis of Fe-Ti Alloys by Mechanical Alloying
Fe-x at%Ti (x=20, 30, 40, 50, 60, 70, 80) were synthesized by mechanical alloying(MA) of Fe powder and Ti powder using a vibrational ball milling for 720ks in 35kPa argon gas atmosphere. The hardness of the MA powders containning from 30at%Ti to 70at%Ti are about 700Hv. The MA powder of Fe-60at%Ti is in the amorphous state in this experimental condition. This amorphous powder was subjected to stress relief at about 627K and was crystallized at 800K. The crystalline phases were FeTi, Fe and Ti. The addition of B to Fe-60at%Ti in MA process promoted to form the amorphous phase.
