摘要：
The present study was undertaken in order to elucidate the effect of the ball-to-powder weight ratio on the amorphization reaction of Al50Ta50 alloy powders using the ball milling technique. As the ball-to-powder weight ratio increases, the rate of amorphization reaction increases drastically, but the content of iron contamination, which comes from the milling tools, increases sharply. A complete amorphous phase is obtained with a ball-to-powder ratio in the range between 36:1 and 108:1 under the present experimental conditions.
