Abstract
Temperature changes associated with the stress-induced martensitic tra nsformation in NiTi have been measured. The magnitude of the temperatu re changes observed depends on the transformation rate and specimen-en vironment heat transfer, with values of approximately 13 K being recor ded for near-adiabatic conditions. The transformation induced temperat ure change was found to have a marked effect on stress-strain behaviou r. Specimen temperatures calculated from a heat balance analysis are s hown to agree well with experimental measurements.
