近二十年来,国外在非晶合金的理论研究和技术应用方面,都取得了很大的进展。非晶合金具有许多特殊的性能,例如:很高的强度和一定的延性,高的抗腐蚀性能,突出的电学性能和磁学性能等。但是非晶态是一种亚稳的结构状态,在一定温度下它将转变为晶态。晶化温度将决定非晶合金的工作温度。此外,有些良好的性能还往往表现在晶化状态下,而且比较稳定。例如,Vitek等在研究非晶Cu-Zr合金时,发现热处理后的完全晶化状态具有最大的硬度值。因此,研究非晶合金的晶化过程具有很大的实际意义。此外,利用非晶合金研究晶化过程有可能进一步弄清许多金属结晶过程方面的问题。这种研究方法
In the recent two decades, great progress has been made in the theoretical research and technical application of amorphous alloys abroad. Amorphous alloys with many special properties, such as: high strength and ductility, high corrosion resistance, outstanding electrical and magnetic properties. However, the amorphous state is a metastable structure that, at a certain temperature, transforms into a crystalline state. Crystallization temperature will determine the working temperature of amorphous alloys. In addition, some good performance is often manifested in the crystallization state, and more stable. For example, when researching amorphous Cu-Zr alloys, Vitek et al. Found that the completely crystallized state after heat treatment has the highest hardness value. Therefore, the study of amorphous alloy crystallization process has great practical significance. In addition, the use of amorphous alloys to study the crystallization process may further clarify many of the problems in the metal crystallization process. This method of research
