The rapid-solidified (RS) melt-spun fiber/ribbon/foil type samples can have very high performance of the metallic actuator/sensor properties by the authors. However, as for the applications of these sample materials in smart material systems, the developed rapid-solidified samples are thought to be inevitably too small force to move the machines and structures in the engineering application. Then, in this paper, we propose one novel material processing technique that can produce the bulk type solid-state actuator/sensor materials by combing the rapid-solidified fiber/ribbon with very short time spark plasma sintering/joining (SPSJ) method. [2] The produced samples, 1) the disk-type sample from stacked layers of RS-ribbons and 2) the sintered compact from ball-milled RS-fibers of Ti50Ni40Cu10 alloy, showed clear thermoelastic phase transformation by DSC evaluation as well as shape recovery. These experimental results show us the effectiveness of the proposed method.
