Abstract
We have investigated the influence of quenches that modify the degree of atomic order on the martensitic transformation of Cu-Al-Be alloys b y calorimetric, ultrasonic and neutron scattering techniques. The chan ges in the thermodynamic quantities and elastic constants induced by c hanges in the degree of order have been compared to reported results f or Cu-Zn-Al alloys. CU-Al-Be has been found to behave differently than Cu-Zn-Al. Some hypothesis accounting for these differences are envisa ged.
