Effect of microalloying on glass-forming ability and crystallization kinetics of Zr52.5Cu17.9Ni14.6Al10Ti5 alloy

Zr52.5Cu17.9Ni14.6Al10Ti5 bulk metallic glass prepared using sponge zirconium was microalloyed with 0.1 at.%B + 0.2 at.%Si + 0.1 at.%Pb. The effect of microalloying on the glass-forming ability and thermal stability of the alloy is studied. The crystallization kinetic parameters are determined by means of a Kissinger plot. The interrelation between these parameters is discussed.
