Abstract

A number of studies on the internal friction of hydrogenated amorphous alloys have been recently performed in order to develop new high damping materials with mechanical strength higher than that of crystalline ones. In this work, effects of hydrogen on the mechanical properties such as fracture strength and internal friction have been investigated in a Ti50Ni25Cu25 metallic glass. It is found that the Ti50Ni25Cu25 metallic glass has high fracture strength even after absorbing hydrogen up to 24.7 at%, while the fracture strength decreases significantly in the high hydrogen content up to about 40 at%. It is also found that the internal friction peak Q−1 is about 5.0×10−2 at 185 K in the case of 40.2 at% hydrogen content. It should be noted that the peak temperature is observed between room temperature and 185 K and decreases with increasing hydrogen content while the peak height increases gradually with increasing hydrogen content.
