Abstract:

The damping capacity of NiTi, Cu-Al-Ni and Fe-Pt alloys is being studied as a function of temperature above and below Ms. Measurements of heat capacity and transformation characteristics have been completed for NiTi and one Fe-Pt alloy and are in progress for a second Fe-Pt alloy and the Cu-Al-Ni alloy. Mechanical property measurements and assessment of the effects of elastic and plastic strains on the characteristics of the Ni-Ti alloy are in progress. The transformation in NiTi alloys is thermoelastic. A plastic deformation can be employed to alter the transformation characteristics.
