that oxygen promotes the precipitation of I-phase and retards the formation of Zr2Cu phase. If the pre-crystallization event for oxygen-induced I-phase is permitted and the main-crystallization event..., Alloy UH had longer onset time within a rather large supercooled temperature range. Phase precipitation corresponding to the main-crystallization peak of Zr65Cu27.5Al7.5 alloy was retarded......
