Abstract
The pressure dependence of crystallization in Zr41Ti14Cu12.5Ni10Be22.5 bulk metallic glass has been studied by means of high-pressure annealing close to and beyond the glass transition temperature, using differential scanning calorimetry and x-ray diffraction. The results reveal that high pressure markedly decreases the crystallization temperature of the glass. It is deduced that high-pressure annealing can promote crystal nucleation by decreasing the work of formation of the critical nucleus, but it also restrains crystal growth by decreasing the diffusion velocity of atoms.Keywords
