METHOD OF THERMOMECHANICAL TREATMENT OF COPPER ALLOYS Russian patent published in 2017 - IPC C22F1/08 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, immediately dealing with technology of copper alloys treatment used in electrical industry for manufacture of parts operating under excessive mechanical loads. The method involves heating copper alloy in the temperature range of 850-980°C and exposure from 0.5 to 2 hours followed by quenching, aging in the temperature range of 350-650°C from 2 to 8 hours, intensive plastic deformation by continuous equal-channel angular pressing in the temperature range of 350-450°C to the true degree of deformation up to 2 followed by rolling at room temperature with a reduction ratio at least 20%.

EFFECT: treatment method provides a semifinished product from copper alloys with an improved package of physical and mechanical properties, ie high strength and high electrical conductivity.
