The superfine form storage alloy wire, the composite material and the production mannered null Ni

摘要

Through phase transformation temperature, it consists of the form memory alloy of the martensitic phase where austenite phase and martensitic phase appear, cold stretching being the wire which was processed, the diameter 60 millimicrons or less, the form memory alloy wire which features that adverse change condition end temperature at least is the 250C is stated. Molding temperature of the glass fiber strengthening resin and the carbon fiber-reinforced resin etc the 180C can obtain the composite material which in the high resin buried the said alloy wire easily without locking the both ends of the wire by using this alloy wire.
