高能球磨制备钛基金属玻璃粉末研究.

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 to 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 hadan improved hardness of 6 615 Mpa, which could be used as an important part in reinforcing materials. [ABSTRACT FROM AUTHOR]
