Cast Pipe Joints of Fe‐15Mn‐5Si‐8Cr‐5Ni‐0.25C Shape Memory Alloy with High Carbon Content

Fe-Mn-Si-based shape memory alloys are the most favorable for largescale applications owing to low cost, good workability, good machinability, and good weldability. However, polycrystalline Fe-Mn-Si-based shape memory alloys have low recovery strains of only 2-3% after solution treatment, although monocrystalline ones reach a large recovery strain of %9%. This review gives an overview of the improvement of recovery strains for polycrystalline Fe-Mn-Si-based shape memory alloys. It is proposed that two fundamental aspects, that is, composition design and microstructure design, shall be satisfied for obtaining large recovery strains of above 6%. Alloying compositions determining the ceiling of recovery strains shall follow three guidelines: (i) Si content is 5-6 wt%; (ii) 20 wt% Mn 32 wt%; (iii) addition of elements strongly strengthening austenite matrix. Microstructure design includes coarsening austenitic grains and reducing twin boundaries as far as possible together with introducing a high density of stacking faults and second phases of strengthening austenite.

A theoretical model is established in order to analyze the stress state and estimate the connecting strength of the iron-based shape memory alloy pipe-connector. The effect of the temperature on the connecting strength is investigated using this model. The results show that the enclasp force of pipe joint P and maximal stresses of pipe and pipe joint ( , ) decreases linearly as increasing temperature. P and ( , ) decrease as increasing the thickness of the pipe joint, the decrease of is less than that of . Therefore, the thickness of the pipe joint is small as much as possible in order to enhance the enclaspe force.
