- Abstract
- Effects of test temperature and alloy composition on dynamic deformation behavior of Zr-based amorphous alloys were investigated in this study. Dynamic compressive tests were conducted in the temperature range from room temperature to 380 degrees C using a compressive Kolsky bar. Dynamic compressive test results indicated that both maximum compressive stress and total strain of the amorphous alloys decreased with increasing test temperature because shear bands could propagate rapidly as the adiabatic heating effect was added at high temperatures. Maximum compressive stress and total strain of the alloy containing ductile beta crystalline phases were higher than those of the monolithic amorphous alloys over the tested temperature range because beta phases played a role in forming multiple shear bands. The alloys having lower T-g or ductile phases had more excellent dynamic properties than the LM1 alloy.
