Abstract
The effects of slight tantalum (Ta) addition on the microstructures, precipitates, martensitic transformation and shape memory performance of Fe–30Mn–6Si-based alloys were investigated. Experimental results show that the slight Ta addition will increase the c/a ratio of ɛ martensite, reduce the Ms temperature and improve the alloy's shape recovery ability. After TMT at 650 °C, the alloy's Ms temperature is reduced and lots of (Fe, Mn)3Si and TaC precipitates form. The effective nuclei and well-aligned precipitates within the grain interior after TMT will improve significantly the alloy's shape memory performance.
