METHOD FOR HEAT TREATMENT OF CASTINGS FROM CARBON-FREE HEAT-RESISTANT NICKEL ALLOYS FOR MONOCRYSTALLINE CASTING Russian patent published in 2013 - IPC C22F1/10

Abstract RU 2485204 C1

FIELD: metallurgy.

SUBSTANCE: after homogenisation and two-stage ageing the proposed material is subject to additional treatment by heating to the temperature of 1100+10°C≤T_to≤(T_{id y'} - 10°C), where T_{id y'} - intensive dilution temperature of γ'-phase in the alloy, exposure at this temperature and cooling at the rate of not less than 50 deg/min.

EFFECT: improving mechanical properties of casting products from carbon-free heat-resistant nickel alloys with monocrystalline structure.
