Abstract

By use of high strength, high elastic strain limit and low Young's modulus of bulk metallic glasses, strain-sensing devices were practically prepared and the performances of the trial products using the devices were investigated. As a result, a Coriolis mass flowmeter constructed from Ti-Cu-based bulk metallic glass pipe exhibits 28.5 times higher sensitivity than conventional flowmeters made from SUS316 pipe. A pressure sensor using a Zr-based bulk metallic glass diaphragm also exhibits 3.8 times higher sensitivity than the conventional sensor using SUS630 diaphragm. These results for the industrial products made of bulk metallic glasses are promising for future developments as industrial materials with high performance.
