This final report describes the effects of strain rate, temperature and long-term thermal aging on the properties of the (Fe,Ni)/sub 3/V long range ordered (LRO) alloys. Tensile tests were performed at room and elevated temperature, and at different strain rates. The macroscopic and microscopic deformation and fracture characteristics, along with controlling mechanisms, were examined using scanning electron microscopy techniques. The ordered alloys were found to have good high-temperature strength compared to conventional fusion alloys such as 316SS. Additionally, the mechanical properties were shown to be insensitive to strain rate and long-term thermal aging. Scanning electron microscopy analyses showed that the deformation and fracture mechanisms change as a function of strain rate, temperature and aging time.
