摘要：
Isothermal grain growth in a mechanically alloyed nanostructured Fe80Ti8B12 alloy was investigated at 915-985 K by TEM and XRD methods. Crystallization of the amorphous phase and grain coarsening stages were observed, and each stage was analyzed using models of a grain growth with dragging of grain boundaries and of normal grain growth, respectively. Activation energies were calculated to be 300 +/- 10 and 280 +/- 10 kJ/mol using the models. (C) 2003 Elsevier Science B.V. All rights reserved.
