Pressure dependence of nanocrystallization in amorphous Fe86B14 and Fe85Cu1B14 alloys

Pressure effect on the nanocrystallization of amorphous Fe86B14 and Fe85Cu1B14 alloys has been investigated by means of piston-cylinder measurements within a pressure range of 0–1.0 GPa. It was found that the pressure does not alter the crystallization products but decreases the crystallization temperature of each crystallization product for both samples. Crystallization products of these amorphous alloys are bcc-Fe, metastable Fe3B and Fe2B, respectively. The crystallization and precipitation temperatures of both alloys decrease with increasing pressure but not in same manner.
