The effect of repeated melting of the mother ingot on the thermal stability of a Zr60Al15Ni25 glassy alloy was investigated by differential scanning calorimetry (DSC). Experimental results indicate that after the repeated melting of the ingots at 1300 and 1580 K, the glass transition temperature Ts increases from 686.4 to 690.7 and 696.8 K and the onset temperature of crystallization Tx from 757.9 to 758.6 and 763.4 K, respectively, indicating that the thermal stability becomes higher after the repeated arc melting of the mother ingot and that it is more effective at higher temperature. Within the framework of structure heredity, the origin of the improvement of the thermal stability of Zr60Al15Ni2s bulk glassy alloy is discussed.
