Considering the amorphous and nano-crystalline cluster structure and their activity, on the basis of the mixed structure Ni-Mo alloys, the crystallization kinetics of the alloys and the performance of the alloys after heat treatment with different mixed structure were studied. The phase structure and composition were determined by X-ray powder diffraction. The crystallization activation energy of the mixed structure was obtained by differential scanning calorimetry. The electrochemical activity of the mixed structure alloy was determined by electrochemical analysis. The experimental results show that the structural stability of the mixed-structure alloy is better, but the crystallization activation energy is much lower than that of the amorphous alloy. The crystallization process consists of a meta-stable structure transition and a new phase formation. The electrochemical properties of the alloy indicated that the alloy with the mixed structure has higher electrochemical activity, with higher hardness and better corrosion resistance, which results from the large true contact surface and the large number of active centers in this material structure.
考虑到非晶态和纳米晶簇结构及其活性，在混合结构 Ni-Mo 合金的基础上，研究了合金的结晶动力学以及不同混合结构热处理后的性能。通过 X 射线粉末衍射确定了相结构和成分。通过差示扫描量热法获得了混合结构的结晶激活能。通过电化学分析确定了混合结构合金的电化学活性。实验结果表明，混合结构合金的结构稳定性更好，但结晶激活能远低于非晶合金。结晶过程包括亚稳结构转变和新相形成。合金的电化学性能表明，具有混合结构的合金具有更高的电化学活性，更高的硬度和更好的耐腐蚀性，这是由于该材料结构中具有更大的真实接触表面和更多的活性中心。
