Problems solved by technology

[0003] At present, the methods for preparing titanium-based metallic glass mainly include gas atomization method and mechanical deformation method. The preparation of metallic glass powder by gas atomization method requires expensive equipment, complicated process, inconvenient operation, low efficiency, and large particle size, making it difficult to achieve low-cost and large-scale production. Preparation; while the efficiency of preparing amorphous powder by mechanical deformation is low, which is not conducive to the realization of large-scale production, and the obtained amorphous powder has a large particle size, which makes the impact toughness and fatigue strength of metal materials not significantly increased, making it difficult to directly apply
