We examined the solidification morphology and structure of arc-melted Zr 50 Cu 40 Al 10 glass-forming alloys. Since the crystal growth rate is much lower than the velocity of isothermal plane of glass transition temperature (T g ), arc-melted Zr 50 Cu 40 Al 10 alloy sometimes reveals glassy phase at finally solidified region (top-side) after crystal growth (bottom side). Vitrification in front of the crystalline solidification interface of arc-melted Zr 50 Cu 40 Al 10 alloy Zr can be seen when
