Figure 1684 shows the dependence of electrical resistivity on temperature for Zr57Al10Ni12.6Cu15.4Nb5 alloy at the heating rate of 15 K/min. The TCR (temperature coefficient of resistance) changes at about 670 K because of glass transition, and suddenly drops at the temperature of ~ 750 K because of crystallization. Tg-dep is the characteristic temperature, while Tx is the crystallization temperature.
