This report relates to the heating effect on the mechanical properties and on "retrogression" of alclad 2024-T3, T4, as well as 6061-T6 Al-alloys which are indispensable, materials for aircraft construction.Summerized results are as follows:1) Aged 2024-alclad alloy revealed clearly retrogression and temper hardening, but showed no secondary age hardening on heating.2) Degree of retrogression can not reach to the equal value of tensile strength with that of solution heat treatment, but showed less tensile strength of 3 to 4kg/mm2 of T3 and T4 condition.3) With 6061-T6 alloy, retrogression did not take place. But with heating up above to the artificial aging temperature, strength decreases with increase of heating time.
