摘要
An Ni-based super heat resistant alloy extruded material manufacturing method includes: (1) obtaining an ingot by casting molten metal having a component composition of a precipitation-strengthened Ni-based super heat resistant alloy wherein the equilibrium precipitation amount of gamma prime at 700° C. is at least 40 mol % and using it as a billet, wherein the billet is heated to a hot working temperature that is at least 1030° C. and is less than the gamma prime solvus temperature of the alloy; and (2) inserting the billet that has been heated to the hot working temperature into a container, imparting a compressive force to the billet from one end side of the container, and extruding the billet at an extrusion rate of 10 to 300 mm/s from a hole in a die placed at the other end side of the container, to yield an Ni-based super heat resistant alloy extruded material.
