Process for making a metal part such as a turbine engine blade reinforcement

摘要

A process for manufacturing a metal part such as a metal reinforcement for the blade of a turbine engine, which includes: manufacturing a three-dimensional metal structure made up of an insert which exhibits properties which allow superplastic forming and diffusion welding to be carried out, and of multiple metal wires encircling the periphery of the insert, where the metal structure forms a preform of the metal part; positioning the metal structure in a forming tool and hot-pressing the three-dimensional metal structure which causes agglomeration of the metal structure so as to obtain the compact metal part.

1. A process for manufacturing a metal part, the process comprising:
manufacturing a three-dimensional metal structure made up of an insert which has properties which allow superplastic forming and diffusion welding to be carried out, and of multiple separate metal wires each encircling a periphery of said insert, wherein a space separates at least two adjacent separate metal wires of the multiple separate metal wires, and wherein said three-dimensional metal structure forms a preform of said metal part; positioning said three-dimensional metal structure in a forming tool, and hot-pressing said three-dimensional metal structure which causes agglomeration of said three-dimensional metal structure, so as to obtain said metal part.
