Phase transition, enhanced diffusion and Y-Al alloy formation are studied using Y implantation with high current extracted from metal vapor vacuum arc (MEVVA) ion source.
The existence of such transformations depends on the alloy system in question and the diffusion process described earlier governs the way in which a given transformation takes place.
