摘      要：The relationship between phase transformation and electric resistivity of Ti-42.6Ni-7Cu SMA was *** the isothermal tensile tests,stress-strain curve shows large hysteresis and nonlinearity,whereas the resistivity-strain curve can be fitted by *** resistivity of SMAs can be determined from the volume fractions of the martensitic and austenitic *** characteristics leads to that the resistance of the SMAs is used as a parameter of strain of SMAs.A SMA actuator using resistance feedback control system was proposed,which can control and retain positioning at any positions without using sensor devices,and the deviation of position of this system was less than 3 μm.
