摘要：
The glass-forming range (GFR) in ternary Ti-Ni-Al alloys was determined via mechanical alloying using a high energy Spex mill. The GFR was also calculated using Miedema's model. Although the theoretical GFR is quite large, the experiments showed a very limited GFR. The concentration ranges chosen were Ti50NixAl50-x (x = 10, 25, 40), Ti60NiyAl4(40-y (y = 10, 20, 30), Ti70Ni15Al15, Ni2TiAl and TiNiAl. Prolonged milling of the amorphous Ti50Ni25Al25 powders led to the reappearance of the crystalline peaks. Calorimetric experiments showed an endothermic peak near 600 K in most of the samples.
