Research Progress on the Tungsten Reinforced Bulk Metallic Glass Matrix Composites

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 to many factors, such as the morphology, size and volume fraction of tungsten, and also to the environmental temperature and strain rate. 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.
