Heat treatment of Nickel alloys
For high resistance to propagation of fatigue cracks propose to handle granular and pressed extra virgin brand according to the mode:
— annealing solid solution TPRγʹ (temperature of complete dissolution γʹ phase) + 10o delayed 1.5 hours;
cooling with a speed of less than 5°C/min to a temperature below TPRγʹ-50°(1100−1050°C);
double aging at 700 °C, day and 800 °C, 4 hours.
The use of such processing does not provide a high heat resistance (at temperatures above 800°C) due to low temperature aging. No annealing before processing on the solid solution leads to raznozernistoy that reduces the level and stability characteristics of the alloy.
Processing method, taken as a prototype, presented in the patent of the Russian Federation 1360232 Method of heat treatment of disks from a complexly alloyed heat-resistant Nickel alloys" (MKI C 22 F 1/10, B. I. 16−94).
Method of heat treatment includes pre-annealing (t° 1100−1180°C) exposure time 4 to 6 hours annealing in solid solution in the interval from TPRγʹ to TPRγʹ+10° regulated cooling, first at a speed of 80−100°C/h to TPRγʹ-40°C, then 40−50°°C/min followed by a 2-step aging while 910−970°C exposure from 6 to 24 hours and cooling to 10−30°C/h up to 800−850°With exposure time of 8−24 hours. According to the authors, the implementation of processing method for alloys ЭП975-ID and ВЖ137-ID allows you to obtain the product without sensitivity to the incision with a 100-hour long strength at 750 °C, equal to 800 and 750 MPa and at 850 °C is equal to 480−440 MPa, respectively for the two alloys.
