Based on the present studies, the microstructure of the as-quenched specimens essentially a single austenite phase. In addition, some lamella structure was found on the austenite matrix. In the meanwhile, the microstructure of the present alloy is also an austenite phase during the 450-650℃ aged processes. Moreover, some stacking faults (similar to dislocation array) could be observed. According to the TEM examined, the foil normal of the stacking faults is (111).
