The long-range order parameter varied linearly with temperature and a significant ordered state was observed at 773K. The DSC measurements showed one main exothermal peak in the temperature range of 493-913K. The maximum rate of energy release occurred at 763±2K with a total thermal effect of ΔH=52±9j/g. The DSC peak showed a shoulder around its maximum temperature of 763±2K which was attributed to order stabilization. The presence of boron in the alloy enhanced the transformation temperature by increasing the enthalpy of vacancies migration without affecting the reaction enthalpy.
