چکیده انگلیسی
Room-temperature mechanical properties of Cu50Zr40Ti10-xNix (0â¤xâ¤4, mole fraction, %) bulk metallic glasses (BMG) with aspect ratios in the range of 1:1-2.5:1 and loading rates in the range of 1Ã10â5-1Ã10â2 sâ1 were systematically investigated by room-temperature uniaxial compression test. In the condition of an aspect ratio of 1:1, the superplasticity can be clearly observed for Cu50Zr40Ti10 BMG when the loading rate is 1Ã10â4 sâ1, while for Cu50Zr40Ti10-xNix (x=1-3, mole fraction, %) BMGs when the loading rate is 1Ã10â2 sâ1. The plastic strain (Ép), yielding strength (Ïy) and fracture strength (Ïf) of the studied Cu-based BMGs significantly depend on the aspect ratio and the loading rate. In addition, the Ïy of the studied Cu-based BMGs with an aspect ratio of 1:1 is close to the Ïf of those with the other aspect ratios when the loading rate is 1Ã10â2 sâ1. The mechanism for the mechanical response to the loading rate and the aspect ratio was also discussed.
