Abstract: The hysteresis behaviour of Cu-Al-X (X=Zn, Mn, Ni) single crystals crystals, of calorimetry in martensitic state is investigated. Tension-compression partial and complete deformation cycles show no dependence on the temperature, a zero-stress diagonal, on which yeld and recovery beginn. "Return point memory" and degradation of hysteresis with deformation amplitude decreasing are found at the pseudo-plastic behaviour.

Thermodynamic transformation parameters and the hysteresis interior of complete and partial thermo-induced, stress-free transformation are received by calorimetry.
