Mechanical properties of crystalline and amorphous Ti alloys
- Tensile and fatigue properties of titanium based bulk metal glass (Ti-BMG) were studied experimentally on the basis of one of the authors task [Okayasu et al., Fatigue and tensile properties of titanium based bulk glassy alloys, Int. J. Marter. Eng. Tech., 5(2011)77]. To understand clearly the mechanical properties of Ti-BMG, commercial crystalline titanium alloy was employed. The ultimate tensile strength of Ti-BMG was about 20% higher than that for the Ti alloy, and that was more than twice high compared to the carbon steel and Al alloy ones. In contrast, different mechanical properties were obtained in the result of fatigue test, where the rapid reduction of the fatigue strength occurred especially in the later fatigue stage, namely the low endurance limit, which was lower than that for the crystalline Ti alloy.
