概要
- 論文の詳細を見る
Fe-Pd alloys containing around 30at.%Pd have face centered cubic (fcc) structure, which is ferromagnetic, and transforms to martensite with face centered tetragonal (fct) structure. The martensite can be induced from the austenite phase by stressing just above the Ms temperature. The magnetization vs. external magnetic field (M-H) curves and stress-strain curves of both austenite and martensite phases were measured. Based on the magnetic and mechanical properties, a new method to utilize the stress-induced transformation is proposed for the actuation mechanism of ferromagnetic shape memory alloy, and compared with the other mechanisms so far proposed, i.e. magnetic field induced transformation, and variant change mechanism. The effects of substituting iron or palladium by platinum, cobalt, or nickel on the mechanical and magnetic properties are examined with respect to their improvement.
