The effect of Al and Ti ratio on glass forming ability and crystallization characteristics of the ball milled Zr-Al-TiCu amorphous alloy composite powders are systematically investigated. The evolution of crystallization phases for the studied alloys during ball milling is CuZr2 +Al2Zr+Ti(Al,Cu)(2) -> Al2Zr+Ti(Al, Cu)(2)+Fe1.945C0.055+Amorphous -> Amorphous+Fe1.945C0.055. However, the duration for the formation of amorphous phase is longer for high Al and Ti ratio alloy than for low Al and Ti ratio alloy. The thermal stability of low Al and Ti ratio amorphous alloy composite powders is lower than that of high Al and Ti ratio ones. The crystallization is more difficult for high Al and Ti ratio alloy composite powders than for low Al and Ti ratio ones. The crystallization mechanism for the two alloys nearly depends on the heating rates and the annealing temperatures. The detailed crystallization mechanism of isochronal and isothermal modes are discussed.
