前言非晶材料在目前的材料科学中占有重要地位。非晶金属在构成金属的原子排列中具有长距离的不规则结构,由于它们不是结晶状组织,因此无晶界,而且组织均匀。不但强度、硬度等机械性能,特别是耐腐蚀性、磁特性极优异,而且能制成广泛的新合金。粉末冶金中的雾化制粉方法稍加改变,便能在粉末的雾化过程中达到快速冷却(冷却速度达10~4～10~8℃/sec),从而使金属粉 Introduction Amorphous materials play an important role in the current materials science. Amorphous metals have irregular structures with a long distance in the atomic arrangement of the constituent metals, and since they are not crystalline structures, they are grain-free and uniform in structure. Not only strength, hardness and other mechanical properties, especially corrosion resistance, excellent magnetic properties, and can be made a wide range of new alloys. In powder metallurgy, the atomization milling method is slightly changed to achieve rapid cooling during powder atomization (cooling rate of 10 ~ 4 ~ 10 ~ 8 ℃ / sec), so that the metal powder
