摘　　要：非晶金属玻璃因其优异力学、物理、化学和机械性能,日益成为复合材料增强体的重要发展方向与研究热点。作为一种稳定、简单、高效的规模化制备技术,机械合金化为构筑非晶金属玻璃粉体提供有效途径。以钛基金属玻璃为研究对象,采用高能球磨技术,实现了非晶粉体颗粒的高效可控制备。借助扫描电子显微镜分析粉体微观形貌,采用X射线衍射仪表征粉体物相结构特性,并使用显微硬度测试仪对其力学性能进行系统测量。结果表明:制备的粉体微颗粒较为均匀,表现出良好非晶结构特征,且非晶粉体硬度提高至6615 MPa,可作为工程增强材料的重要组成部分。Amorphous metallic glass has excellent mechanical,physical,chemical and mechanical properties,and is an important development direction and research hotspot of metal composite reinforcements.As a stable,simple,efficient and scalable technology,mechanical alloying provides an effective way to prepare amorphous metal glass.In this work,titanium-based amorphous metallic glass was used as the research object,and the mechanical alloying method was used to achieve efficient and controllable preparation of amorphous powders.The micro-morphology of sample surface was analyzed with the help of scanning electron microscope,amorphous phase structures were characterized by X-ray diffraction,and mechanical properties were measured by micro hardness tester.The results show that the prepared metal powders were relatively uniform and had good amorphous structure characteristics.The hardness test shows that as prepared amorphous metal powder had an improved hardness of 6615 MPa,which could be used as an important part in reinforcing materials.
