Abstract
Recently, it is attempted to apply high manganese steel including Fe-based shape memory alloy to vibration dampers. Especially, the alloy indicates a special characteristic as a well-known shape memory effect. By coupling between this effect and its plastic deformation, it can be considered that its deformation behaviour at higher deformation rate becomes quite complicated and still unclear. In this study, tensile tests of Fe-based shape memory alloy at different rate of deformation are conducted by using two different testing apparatuses such as the conventional material testing machine and impact testing machine based on the split Hopkinson pressure bar technique. In the tests, temperature rise is captured during the quasi-static deformation. After the quasi-static test, the recovery strain due to shape memory effect is measured by heating up the deformed specimens to Af temperature. Finally, the rate sensitivity of the alloy is discussed including the recovery strain.
Highlights
It is attempted to apply high manganese steels to vibration dampers with high performance
Its production cost is cheaper than other shape memory alloy (SMA) [3]; the alloy is attempted to be applied to large-scale structural members [4] such as the joint in the pipeline [5]
It is important to investigate the rate sensitivity of the Fe-based SMA. From this point of view, Ogawa and Yamada [7] investigate the rate sensitivity and temperature dependence of tensile deformation behaviour in Fe-14Mn-6Si-9Cr-5Ni alloy by using both the material testing machine and impact testing machine based on split Hopkinson pressure bar (SHPB) technique

It is attempted to apply high manganese steels to vibration dampers with high performance. It is important to investigate the rate sensitivity of the Fe-based SMA From this point of view, Ogawa and Yamada [7] investigate the rate sensitivity and temperature dependence of tensile deformation behaviour in Fe-14Mn-6Si-9Cr-5Ni alloy by using both the material testing machine and impact testing machine based on split Hopkinson pressure bar (SHPB) technique. As the result, they reported that positive rate sensitivity as similar to the metallic materials can be seen. The rate sensitivity of the alloy is discussed including the recovery strain
