| Research Abstract |
n the shape-memory composite belt laminated with two kinds of shape-memory alloy tape and shape-memory polymer film, three-way deformation properties appear during heating and cooling. If the nitrogen ion is implanted to the shape-memory alloy wire, the fatigue life becomes longer. In the shape memory alloy subjected to the stress-controlled subloop loading, creep or creep recovery and stress relaxation or creep recovery appear. The torsional fatigue life curve of the shape-memory alloy tape is expressed by a power function. Two kinds of small actuator models, an automatic opening and closing door and an automatic opening and closing blind, were developed by using two kinds of shape-memory alloy tapes showing shape memory effect and superelasticity.
