FIELD: metallurgy.
SUBSTANCE: alloy Al-Cu-P is introduced into melt with contents of phosphorus 10-14%; prior to introduction alloy is subject to ultrasonic treatment in mode of developed cavitation at temperature 30-50°C above temperature of alloy liquidus. Further conditioning, tapping of alloy and cooling are performed. Alloy Al-Cu-P is introduced into melt in form of ingots, small pigs, granules or in liquid state.
EFFECT: upgraded plasticity and fatigue strength of items at higher temperatures.
