摘要：
Mechanically alloyed Fe75Nb5Ge20 alloys have been studied using different TEM techniques. For short milling times the microstructure of the system consists of an inhomogeneous mixture of the starting crystalline phases: small bcc Fe nanocrystallites, filament-like bcc Nb and spherical fcc Ge. After long milling times, the microstructure consists of a single bcc supersaturated solid solution Fe(Nb,Ge) phase. (C) 2010 Elsevier B.V. All rights reserved.
