摘要：
The effect of long-term room temperature ageing on structure and thermal stability of as-cast and inhomogeneously deformed Pd40Ni40P20 metallic glass has been investigated. It is found that the first crystallization peak temperature decreases and this indicates that the thermal stability decreases after ageing for these as-cast and inhomogeneously deformed metallic glass samples. The high density of shear bands formed after deformation disappears and nanocrystallization has been observed after ageing for the inhomogeneously deformed Pd40Ni40P20 metallic glass.
