Abstract
Ti50Ni50-xCux(x=0,5,10,15at%) fine fibers(diameter= φ 80 μm, length=20cm∼1m) were successfully developed by the arc-melted rapid-solidification method. It has been very difficult to do the conventional melt-work processing from the bulk material of this alloy to very fine fiber because of the brittleness from metallic compounds especially in the range of Cu≧8at%. The fibers showed good shape memory effect. As Cu content increased, the temperature hysteresis (ΔT=Af-Mf) of recovery strain-temperature curves as well as DSC curves became smaller and the tensile strength showed more than 1000MPa in Ti50Ni40Cu10at% fiber. Therefore, the developed rapid-solidified, thermoelastic fine fiber actuator/sensor materials have high potentially of applications for micro-machines and the fillers of smart composites.
