Embodiment 1
[0017] A process for preparing a nickel-based superalloy. The superalloy consists of the following components in weight percentage: 22.5% Cr, 8.0% Co, 6.5% W, 4.0% Mo, 1.2% Al, 2.5% Ti, Nb 2.0%, Mn 2.0%, Fe 2.0%, B 0.08%, Ce 0.5%, C ≤ 0.1%, Si ≤ 0.2%, P ≤ 0.008%, S ≤ 0.008%, Ni balance; the preparation process includes the smelting process and heat treatment process, the smelting process is to use a vacuum induction furnace to melt the master alloy, and perform directional solidification in a liquid metal directional furnace to prepare a oriented columnar crystal alloy. The vacuum degree of the directional furnace is about 1×10 -4 mmHg, the pouring temperature is about 1600°C, the drawing speed is about 4mm / min, the temperature gradient is about 85°C / cm, and the liquid tin temperature is about 250°C. 3h, air-cool to room temperature; reheat to about 1170°C, keep for about 3h, air-cool to room temperature; reheat to about 950°C, keep for about 8h, air-cool to room temperature. ...
