FIELD: metallurgy.
SUBSTANCE: invention can be used for control of the service life of the items made from A85 grade aluminium and operated under creep conditions. Creep control method of A85 grade aluminium involves attachment to the item from aluminium of one of the metal plates having work function that is different from aluminium. At attachment of the above plates the contact difference of potentials appears. Depending on value of potential contact difference the creep process is either slowed by connection of plate from Pb, Ti, Fe, Cu, or accelerated by connection of plate from Zr, Ni.
EFFECT: increasing service life of aluminium items.
