TiNiCu Martensitic Transformation Characterization at Low Stress Levels through Thermomechanical Cycling

Abstract:

This investigation has studied the characterization of the thermomechanical behaviour of a TiNiCu shape memory alloy with different heat treatments. This characterization has been done by analyzing martensitic transformation at constant stress tests. The martensitic transformation was analyzed by measuring electrical resistance and strain. The results showed that orientation is reached at different stress levels during each heat treatment; low stress thermomechanical cycling does not affect transformation temperatures and thermomechanical cycling at upper stress levels produces different changes of behaviour depending on the stress level and/or heat treatment.
