The coherent precipitates inherited by the martensite crystals change the transformation parameters. Nonmonotonous change of temperature hysteresis width of $\beta_1$ $\leftrightarrow$ $\gamma'$ transformation versus aging time has been revealed. New approach was proposed to explain the nature of thermal hysteresis of the thermoelastic Martensitic transformations.
