Abstract

Phase separated Pd_41.5Ni_41.5P_17.5 bulk metallic glasses (BMGs) were subjected to isothermal annealing at 613 K for different time periods, t, in the range of 0 ≤ t ≤ 8 h. For 0 ≤ t ≲ 5 h, crystalline precipitates, in the shape of spheres, appear and its density is more or less a linear function of t. They are randomly distributed in the amorphous matrix. For t ≲ 5-6 h, the density of the crystalline precipitates increases rapidly. In addition, they are no longer distributed randomly in the phase-separated amorphous matrix. Clustering is displayed. Experimental results suggest that the clustering is due to cubic crystalline precipitates which start to appear when t ≈ 5-6 h.
