英文摘要	(Zr0.761Cu0.147Ni0.092)93-xAl7+x bulk amorphous alloys with x of 0, 1, 2, 3, 5, 7 (mole fraction, %) were prepared by copper mold casting method. The differential scanning calorimeter (DSC), universal testing machine and micro-hardness tester were employed to detect the supercooled liquid region, mechanical properties and microhardness of the samples, respectively. Furthermore, the relationship between microstructures and mechanical properties of the BMGs was analyzed by X-ray diffraction (XRD) and scanning electron microscope (SEM). The results show that, with the addition of the content of Al, the glass transition temperature Tg and initial crystallization temperature Tx of (Zr0.761Cu0.147Ni0.092)93-xAl7+x (x=0, 1, 2, 3, 5, 7 (mole fraction, %)) amorphous alloys increase. But the supercooled liquid region ΔTx of amorphous alloys firstly increases and then decreases, and it reaches 94 K which is best in the supercooled liquid region ΔTx of the alloys when x=3. The plastic deformation increases first and then decreases with the Al content increasing and the plastic deformation reaches the highest value of 15.82% while x is 3. Along with the increase of the content of Al, the yield strength σs and microhardness HV of the alloy have an enhanced trend, and both of them reach the highest value of 1713 and 4095 MPa while x is 7. © 2017, Science Press.
