AbstractThe effect of W volume fraction (V-f) on dynamic mechanical behavior of W fiber/Zr-based bulk metallic glass composites (W-f/BMGCs) was investigated by split Hopkinson pressure bar (SHPB) and finite element method (FEM). The yield strength increased with the increase of V-f under both quasi-static and dynamic compression, and the dynamic flow stress is obviously greater than that under quasi-static compression. The fracture strain also increased with the increase of V-f under dynamic compression, which is different from that the composite with similar to 70 vol% W exhibited the highest fracture strain under quasi-static compression. With the increase of V-f under both quasi-static and dynamic compression, the failure mode of the composites changed from shearing to a mixture of shearing and splitting, and lastly only splitting. High strain rate suppressed macro-shearing but promoted micro-shearing and splitting compared to that under low strain rate, which is suggested to be the reason why the composites exhibited different rules of strain rate-related fracture strain under quasi-static and dynamic compression.
