2. Materials and Methods. Master alloy ingot with the composition Ti 50 Cu 25 Ni 20 Sn 5 (at.%) was prepared by arc melting of pure metal mixtures (min. 99.9 wt %) with a Ti-getter under purified argon atmosphere. It was impossible to crush the as-cast ingots into fine chunks (or coarse powder) for further ball milling, even using a heavy sledgehammer.
An Ti 50 Fe 50 alloy ingot was prepared by arc melting Ti (99.9%) and Fe (99.9%) and was remelted several times under an argon atmosphere.
