| Abstract: | Iron-based shape memory alloys have recently attracted widespread attention due to their low cost, excellent workability,machinability and good weldability, and has been identified as a new shape memory material with promising development. Mechanical alloying (MA) and powder metallurgy (PM) are new methods for the preparation of materials, which can be used to prepare shape memory alloy with superior properties. The effect of MA and PM on the phase transformation, microstructure and properties of Fe-Mn-Si-based shape memory alloys, and the application of such alloys in new fields were discussed in details. At last, the problems in the study of MA/PM process for preparing Fe-Mn-Si based SMA, such as process parameters, phase transformation mechanism, recovery stress and low temperature stress relaxation are pointed aod. |
