摘　　要：采用DSC、TGA、XRD等实验手段研究了大块非晶合金Zr55Cu30Al10Ni5各种状态的氧化行为。结果表明非晶态样品的氧化速率最快,稳定晶化态样品的氧化速率最慢,这说明晶态相Zr2Cu具有良好的抗氧化性。非晶态和晶态样品的氧化动力学均遵循线性规律。The oxidation behavior of bulk amorphous alloy Zr55Cu30Al10Ni5 in different states was investigated by means of DSC, TGA and XRD. It is found that, the oxidation in amorphous state is fastest, but the oxidation in the stable crystalline state is the slowest. This demonstrates that the final crystallization phase of Zr2 Cu exhibits a very good resistance against oxidation. The oxidation kinetics of a linear law. the sample in amorphous and crystalline state also follows
