FIELD: non-ferrous metallurgy, possibly working parts of Silumins.
SUBSTANCE: method comprises steps of performing cycle aging-quenching- aging. Soaking time period at temperature for heating at quenching and at aging is in range 15 - 30 min. Cycle quantity of heat treatment is one or more. Invention provides lowered linear expansion factors of Silumins in temperature range 150 - 300°C.
EFFECT: lowered linear expansion factor of Silumins.
