To determine the optimized composition of quaternary Zr-Cu-Ni-Al bulk glassy alloy, its thermal and mechanical properties are examined. Zr shows high correlation coefficients with Tg and Vickers hardness, whereas Ni and Al show high correlation coefficients with Tl and Tx, respectively. Only Cu shows no remarkable correlation coefficient with any thermal or mechanical properties. We conclude that a compositional region with a high (over 135 kJ/m2) U-notch Charpy impact (CUE) value is located around the Zr52Cu30Ni8Al10 bulk glassy alloy, which exhibits a maximum CUE of 165 kJ/m2. Moreover, a compositional region with high tensile strength (over 2000 MPa) is also located around the Zr48Cu32Ni8Al12 bulk glassy alloy, which shows a maximum tensile strength of 2100 MPa.
