Research Progress on the Tungsten Reinforced Bulk Metallic Glass Matrix Composites

摘要:

钨增强块体非晶复合材料属于一种新型材料,具有高强度、高硬度和耐磨损等优质性能,而且还具有非常优越的穿甲性能,在国防军事上有广阔的应用前景。所以国内外学者对钨增强块体非晶复合材料的制备方法、准静态和动态的力学性能和侵彻穿甲方面进行了广泛的研究,研究表明,钨增强块体非晶复合材料的性能与增强相钨的形态、体积分数、直径、环境温度、应变速率等密切相关。本文综述了钨增强块体非晶复合材料的国内外研究现状,并对其制备方法、力学性能和侵彻穿甲性能三个方面在不同影响因素下的差异性进行了总结和归纳,同时对未来的研究工作和方向进行了展望。

Abstract:

Tungsten reinforced bulk metallic glass composites (BMGCs) possess the high strength, hardness, wear resistance and excellent armor penetration performance, resulting in a promising application prospect in military industry. In the past decades, scholars all over the world have paid much attention to the preparation methods, mechanical properties (quasi-static/dynamic) and armor penetration behavior of tungsten reinforced BMGCs. It has been found that the performance of tungsten reinforced BMGCs is closely related with many factors, such as the morphology, size and volume fraction of tungsten, and also the environmental temperature and strain rate etc. The review summarizes the research progress of tungsten reinforced BMGCs, including the preparation methods, mechanical properties and armor-piercing properties under different influencing factors. Finally the direction of research and development of tungsten reinforced BMGCs are also prospected.
