Title: Extrusion properties of a Zr-based bulk metallic glass
Author(s): Yu, G. S.; Lin, J. G.; Li, W.; Wen, C. E.
Abstract: The extrusion behavior of Zr41.2Ti13.8Cu12.5Ni10Be22.5 metallic glasses in the supercooled liquid region was investigated. Good extrusion formability was observed under low strain rates at temperatures higher than 395 °C. The metallic glasses were fully extruded without crystallization and failure within the range of T = 395–415 °C under strain rates from 5 × 10− 3 s− 1 to 5 × 10− 2 s− 1, and the deformation behavior of the metallic glasses during the extrusion was found to be in a Newtonian viscous flow mode by a strain rate sensitivity of 1.0.
