Effect of Ti addition on mechanical properties of Zr-based bulk metallic glasses
Source abstract
Abstract
The effect of Ti substitution for Cu on the glass forming ability (GFA) and mechanical properties of Zr 60Cu (20-x)Al 10Ni 10Ti x ( x = 0, 1, 3 and 5at.%) bulk metallic glasses (BMGs) were investigated in present paper. With the increase of Ti content, the supercooled liquid region range increases from 47 K to79 K, which indicates that the GFA of Zr-based BMGs is improved. The plasticity and fracture strength of Zr-based BMG without Ti addition is 9.8% and 1778 MPa, respectively. The plasticity of Zr-based BMGs significantly increases with Ti addition, reaching the peak value of 25.3% when the Ti content is 3 at.%. Meanwhile, the corresponding fracture strength is increased to 2315 MPa. In addition, the hardness and elastic modulus of Zr based BMGs were also significantly improved with the addition of Ti. The deformation and plasticization mechanisms after minor Ti addition to Zr-based BMGs are also discussed and analyzed.
