High pressure high temperature devitrification of a Fe85Si10B5 and a Fe78B13Si9 metallic glass was conducted at constant pressures with simultaneous in situ energy dispersive x-ray powder diffraction measurement. After the application of pressure a constant heating rate was applied. Heating the sample in each case resulted in crystallization with two distinct stages. Pressure is found to strongly affect crystallization temperature. Each stage of crystallization is identified using crystallographic analysis. Complementary high pressure room temperature studies were conducted for each sample.
