Abstract

The compression tests were conducted on four Zr-based bulk metallic glasses (BMGs) with different Nb contents. The results show that the addition of few percent Nb did not change the mechanical property. At 77 K, the strength increased notably without embrittlement. Furthermore, it is suggested that the normalized strength changes linearly with the normalized temperature. Current results provided important evidences that BMGs have a great application perspective at cryogenic temperatures. In addition, it is found that at ambient temperature, the BMGs do not exhibit strain rate sensitivity. However, the strength is dependent on the strain rate at high and cryogenic temperatures.
