Influence of Heat Treatment Process on Shape Memory Effect in Fe-Mn-Si Alloy

    Graphical Abstract
    • Abstract
  • Influence of heat treatment process on shape memory effect (SME) inFe-28Mn-4Si (adding microelement Magnesium) alloy were studied. The results show thatSME of alloy originates from stress induced γ-ε martensitic transformation and itsreversible transformation, SME can be improved by thermal mechanical training treatmentand solution treatment by strengthening austenitic matrix. When the inside diameter of hotrolled seamless alloy pipes is expended by 5%, the strain recovery ratio will be 45%, andthis strain recovery ratio is enough for pipe joints.
