| Research Abstract |
We investigated to improve simultaneously ferromagnetic and shape memory properties of Fe-Cr-Si-Mn-R (R: rare earth), and optimal compositions and suitable heat-treatment conditions were clarified. In addition, the magnetic properties were numerically modeled as a function of temperature and stress and computer aided finite element designing of actuators was enabled. Moreover, bilayer ribbons, which have both shape memory layer and magnetic layer were newly developed by single-roll melt spinning technique and their fabrication conditions were made clear.
