METHOD FOR MANUFACTURING A MODULE HAVING A HOLLOW AREA BY MEANS OF HOT ISOSTATIC PRESSING

摘要

The invention relates to a method for manufacturing a module (2) having a hollow area by means of hot isostatic pressing, including: a step of making an assembly including vertically adjacent elements defining the hollow area, said assembly being made so as to form a sealed casing containing said hollow area, comprising at least one fusible blocking member (12) separating the hollow area from the outside of the assembly; and a step of hot isostatic pressing said assembly, carried out so as to achieve a diffusion welding of the elements thereof, said step being carried out by varying the temperature and pressure conditions such that the latter cause, during said step, a breakage of the fusible blocking member (12) enabling the pressurizing gas to enter into the hollow area (2).
