Research Progress of Fe-Based Superelastic Alloys

In recent years, superelastic alloys have become a current research hotspot due to the large recoverable deformation, which far exceeds elastic recovery. This will create more possibilities in practical applications. At present, are widely used fields of machinery, aerospace, transmission, medicine, etc., and smart materials with great potential. Among alloys, Fe-based advantages low cost, easy processing, good plasticity toughness, wide applicable temperature range. The progress reviewed this paper. mechanism thermoelastic martensitic transformation its relation superelasticity summarized. effects precipitate, grain size, orientation, texture on discussed detail. It is expected provide guide development understanding alloys. future prospected.
