Embodiment 1
[0026] After the alloy ingot is homogenized and annealed at 1150°C for 15 hours, it is forged at 1200°C into a 60mm×60mm billet, and then hot-rolled at 1150°C into a Φ25mm bar. Finished bar heat treatment process: heating at 1050°C for 1 hour, water quenching to room temperature; heating at 820°C for 1.2 hours, air cooling to room temperature; finally aging treatment at 480°C for 8 hours, air cooling to room temperature.
Embodiment 2
[0028] After the alloy ingot is homogenized and annealed at 1180°C for 12 hours, it is forged at 1160°C into a 70mm×70mm billet, and then hot-rolled at 1180°C into a Φ30mm bar. Finished bar heat treatment process: heating at 1100°C for 0.5h, water quenching to room temperature; heating at 810°C for 1.5h, air cooling to room temperature; finally aging treatment at 520°C for 6h, air cooling to room temperature.
