Abstract The disorder-induced excess energy,δL α, of aβ-Cu1− x)(ZnAl) x (0.30 ≲x ≲ 0.35) alloy, which shows a martensitic transformation at low temperature, after quenching from different initial temperatures,T i, is calculated. Ordering-energi-es for the different nearest and next-nearest neighbour atom pairs, obtained by fitting mean field expressions of order-disorder critical temperatures to experimental data, are used. The excess energy is related to the changes of the latent heat of the martensitic transformation,δL, observed just after quenching from Ti. It was found that the shift in latent heat correlates linearly with the calculated excess energy of theβ-phase. Calorimetric measurements justify the results.
