Abstract:
Amorphous Fe 79 Ti 16 P 5 alloy powders were synthesized from commercially available elemental powders by mechanical alloying. The microstructure, thermal stability and crystallization kinetic of as-milled powders were analyzed by XRD, SEM and DSC. Moreover, bulk ultrafine-grained materials were fabricated through spark plasma sintering of the amorphous powders. Results show that the amorphous powders exists two exothermal peaks during crystallization process. The effective activation energies for crystallization are obtained 109.14 kJ/mol and 205.97 kJ/mol for E p1 and E p2 , respectively, by using the Kissinger method. The mechanical properties of the bulk materials are remarkably improved with the increase in the sintering temperatures. The ultimate compressive strength increases from 1282 MPa to 2015 MPa, but absence of ductility.
