  • Crystallization products of amorphous (Fe0.99Mo0.01)78Si9B13 (FMSB) alloy or pure amorphous FMSB alloy reacted with Al are different under high pressure. The amorphous FMSB alloy reacted with Al may start crystallization at Al/FMSB interface by reacting diffusely with Al. It crystallizes to -Fe (Al) and second-amorphous phase in the range from 3.0 to 5.0 GPa in the temperature range of 780 K to 900 K and to -Fe (Si), Fe3B or Fe2B beyond the range of 3.0 to 5.0 GPa between temperatures of 720 and 900 K. The effect of pressure and temperature on its crystallization process comes mainly from the change of Gibbs energy of -Fe solid solution with pressure, temperature and Al content.
