Abstract

By self\|developed differential vacuum pressure casting technology Cu47Ti34Zr11Ni8 bulk amorphous alloy with the shape of rod and sheet was prepared

and the thermal stability of the amorphous alloy was examined. The results showed that the rod sample with maximum diameters up to 3 mm and the sheet sample with maximum thickness up to 1 mm can be obtained. The amorphous alloy with glass transition temperature （ T g） 672 K

crystallization temperature （ T x1） 735 K

temperature interval of supercooled liquid region △ T x 63 K and reduced glass transition temperature （ T rg ） 0.575 has excellent thermal stability.
