Effect of Microalloying on Glass-Forming Ability and Crystallization Kinetics of Zr_(52.5)Cu_(17.9)Ni_(14.6)Al_(10)Ti_5 Alloy

摘要

Zr_(52.5)Cu_(17.9)Ni_(14.6)Al_(10)Ti_5 bulk metallic glass prepared using sponge zirconium was microalloyed with 0.1 at. percent B + 0.2 at. percent -Si + 0.1 at. percent 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.
