Abstract
Abstract
The crystallization process in a Zr-based bulk metallic glass with the composition Zr44Ti11Cu10Ni10Be25 was studied during isothermal annealing above the glass transition temperature at 682 K. Indentation creep tests were applied to study the effect of crystallization on the viscosity. It was found that the increase in viscosity during crystallization is primarily caused by the hard crystalline grains and secondarily by the change of the chemical composition of the remaining liquid phase. The deformation behavior at room temperature is studied by three-point bending tests. The strength of the specimens decreases significantly in the first step of the crystallization process.
