Abstract

Effects of annealing on structural evolution and microhardness of Zr50Cu40-xAl10Pdx (x=0-15) bulk metallic glasses (BMGs) and composites were investigated using X-ray diffraction (XRD) and micro-hardness analysis. The glass transition temperature Tg and the crystallization temperature Tx of Zr50Cu40-xAl10Pdx (x=0-15) BMGs are 703-728 K and 758-764 K, respectively, determined from differential scanning calorimetry (DSC) with heating rate of 10 K/min. The BMG samples were annealed at different temperatures (below Tg, between Tg and Tx, and above Tx) and for different time period (5 min, 10 min, 20 min, 30 min), and then cooled in air. Based on XRD analysis, the as-cast BMG samples and the samples annealed at 623 K (i.e. below Tg) showed amorphous structures, and the samples annealed at 723-923 K (i.e. above Tg) for 30 min showed amorphous-crystalline composite structures. Microhardness measurements indicated that with increasing annealing temperature, microhardness gradually increased and then leveled off.
