Abstract

A Fe/NiTi composite wire fabricated by simple mechanical processing exhibits a singular deformation feature of strain recovery ratio increase with increasing tensile strain, which is diametrically opposite to that of conventional metal materials. Furthermore, the composite possesses a recoverable strain of over 7 and a higher mechanical damping capability than that of the well-known high damping NiTi shape memory alloy. In-situ synchrotron X-ray diffraction reveals that these extraordinary features originate from the strong interaction between the soft Fe core and the superelastic NiTi tube during tensile cycling. This study offers in-depth understanding of the deformation behavior of the composites composed of soft metal and superelastic shape memory alloy. © 2012 American Institute of Physics.
