摘要：
The influence of heat treatments on the structure and the mechanical properties of a Zr55Cu30Al10Ni5 bulk metallic glass is studied. Cyclic treatments above 480 degreesC lead to quite unchanged elastic moduli and hardness, while the thermal expansion coefficient keeps decreasing with rising annealing temperature above 460 degreesC, whereas a monotonous treatment rises respectively the elastic moduli and the hardness by 30% and 13%.
