摘要:	The as-quenched microstructure of the Fe-23 at.%Al-8.5 at.%Ti alloy was a mixture of (A2 + D0(3)) phases. Transmission electron microscopy (TEM) examinations indicated that when the alloy was aged at 900 degrees C, the size of the D0(3) domains increased with increasing aging time, and an A2 -> (A2 + D0(3)) -> (B2 + D0(3)) transition occurred at a/2(100)anti-phase boundaries (APBs). This feature has never been reported by other workers in the Fe-Al-Ti alloy systems. (c) 2007 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
