Shape-memory effect and strengthening mechanism in a Nb and N-doped Fe-Mn-Si-based alloy
Effect of alloying additions on the SFE, Neél temperature and shape memory effect in Fe–Mn–Si-based alloys
A range of Fe–Mn–Si-based shape memory alloys has been investigated to examine the interplay of composition, stacking fault probability (SFP) and Neél temperature on the shape memory effect (SME). It has been found that the SFP (inversely proportional to stacking fault energy) showed little correlation to the SME for the range of alloy compositions examined. Further, the Neél temperature was not found to exhibit a significant effect on the SME. The addition of interstitial elements, however, was found to markedly decrease the SME.<br /
