Abstract

The realisation of the recoverable strain variation by ultrasonic vibrations was studied in shape memory bimetallic strips produced by explosion welding. Two bimetal “Ti49.4Ni50.6–AISI 304” and “Ti50Ni50–Ti49.3Ni50.7” strips were deformed to 5% and subjected to ultrasonic vibrations. It was found that the strain variation initiated by the ultrasonic vibrations was characterised by a larger recovery strain and occurred at lower temperatures than during conventional heating. This was caused by the simultaneous action of the ultrasonic heating and the repeating variable stress that increased the mobility of the interfaces.
