Abstract

The effect of partial substitution of Ti for Zr on the glass-forming ability was studied in Cu50Zr45-xTixAl 5 (x = 0, 2.5, 5, 10) alloys by using thermal analysis and X-ray diffractometry. The glass transition temperature, Tg, of Cu 50Zr45-xTixAl5 alloys decreased from 707 K at x = 0 to 700 K at x = 2.5, and keeps almost constant with further increase of x. On the other hand, the crystallization temperature, T x decreased gradually from 767 K at x = 0 to 741 K at x = 10. The partial substitution of Zr by Ti in Cu50Zr45Al 5 alloy promotes the glass formation. The maximum diameter for glass formation by injection casting increased from 3 mm for Cu50Zr 45Al5 alloy to 4 mm for Cu50Zr 42.5Ti2.5Al5 alloy.
