Abstract

The invention discloses a preparation method for recycling GH4169 alloy cold-drawn rods, which comprises the following steps: A. using a billet cutting machine to perform rolling and billeting of a Φ160mm GH4169 alloy steel rolling billet; B. using a billet cutting machine to The steel slab treated in step A is subjected to secondary rolling; C, solution annealing; D, surface polishing treatment after solution; E, cold drawing. The invention can improve the deficiencies of the prior art and improve the strength performance of the material.

Description

technical field [0001] The invention relates to the technical field of alloy material preparation, in particular to a preparation method for recycling GH4169 alloy cold-drawn rods. Background technique [0002] GH4169 alloy is a nickel-based deformed superalloy, which is widely used in the core components of engines such as aero-engine turbine disks, turbine shafts, and fasteners. As the customer's requirements for the strength of GH4169 alloy rods are greatly improved, the traditional hot rolling can no longer meet the strength requirements of the model standard (room temperature tensile strength ≥ 1515Mpa, room temperature yield strength ≥ 1380Mpa). Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation method for recycling GH4169 alloy cold-drawn rods, which improves the strength performance of the material. [0004] In order to solve the above technical problems, the technical solutions adopted by the...
