Abstract

The microforming behavior of Zr_41.2Ti_13.8Cu_12.5Ni₁₀ Be_22.5 bulk metallic glass (Vit.1) in the supercooled liquid region was investigated. The stress-strain relations for Vit.1 were established in uniaxial compression tests using the microforming system. Firstly, the effects of forming time, temperature and punch velocity on the flow stress of the specimens with a typical size of d1 mm × 1.5 mm were analyzed. Further more, the effects of the specimen size were discussed. The results indicate that the flow stress of Vit.1 decreases with the specimen size decreasing. Based on the research, the Vit.1 microgears with reference diameter of 1 mm were fabricated by closed die forging and observed by SEM. The results show that the Vit.1 microgears can be formed successfully in the supercooled liquid region using the microforming technology.
