GH98 alloy forged rod and preparation method thereof

The invention discloses a GH98 alloy forged rod and a preparation method thereof, and relates to the technical field of high-temperature alloy forging.The method comprises the steps that S1, smelting is conducted, specifically, a GH98 high-temperature alloy cast ingot is obtained through a VIM + VAR smelting process; s2, primary homogenization: carrying out two-stage homogenization heat treatment on the cast ingot obtained in the step S1; s3, swage anvil low-speed pre-forging is conducted, specifically, a V-shaped anvil is adopted for low-speed pre-forging of the arc starting end of the cast ingot obtained in the step S2, constant pressure is kept after the size is reached, then an ingot body is shaped, and a clamp handle is hit at the feeding end; and S4, upsetting and drawing to form a material, wherein upsetting and drawing cogging or direct drawing cogging is adopted. According to the method for reducing the forging cracking of the W and Mo reinforced high-temperature alloy end, the problem of forging cra
