Quasi-Static and Dynamic Compressive Characteristics of Tungsten Fiber/Zr-Based Bulk Metallic Glass Matrix Composites
Quasi-static and dynamic compressive characteristics of Zr41.25Ti13.75Cu12.5Ni10Be22.5 metallic glass matrix composites reinforced by tungsten fiber were investigated with different strain rates, the results showed that the compressive yield strength of W f/Zr-based metallic glass matrix composites with fiber volume fraction of 40% was up to 2300 MPa, and the strain was up to 24% under the strain rate of 1 × 10–4 s–1; Dynamic compressive strength of the composites increased with the strain rate below 3000 s–1, and the fracture mode was mainly shearing and splitting, similar to that of quasi-compression.
