Abstract
Among various kinds of shape memory alloys, a Fe-based alloy indicates excellent formability, machinability and weldability. Additionally, its production cost is lower than other alloys. Therefore, it is attempted that the alloy be applied to structural members such as joints for pipelines, splice plates for railways, bolts and nuts, etc. When the alloy is employed for such applications, it is unavoidable to deform flexibly at higher loading rate because of earthquake, typhoon and related natural disasters. Thus, it is important to investigate rate sensitivity of the alloy. In this study, experimental research works done by the authors on the rate sensitivity of deformation and transformation behavior in Fe-based shape memory alloys are summarized with reviewing some related papers.
