A study of the glass forming ability in ZrNiAl alloys

The melting and solidification behavior of ZrNiAl alloys were studied. Near one eutectic point, several alloys were found exhibiting a good glass forming ability (GFA) and amorphous rods of 2, 5 and 8 mm in diameter were cast. Zr60Ni21Al19 alloy was found to exhibit excellent GFA and amorphous rods with 8 mm in diameter were successfully cast. All the alloys exhibit the same melting temperature, which indicates that they belong to the same ternary eutectic system.
