The materials used in combustion chambers are exposed to high temperatures and significant stresses that cause changes in microstructures and mechanical properties over time. It is therefore important to quantify and integrate these microstructural evolutions in the dimensioning of structural parts. The experimental characterization of these materials at fine scales equivalent to the order of magnitude of the generated microstructural gradients remains delicate, especially at high temperature. In order to make this characterization feasible, the OGFPA project funded by the Quebec Ministry of Economy, Science and Innovation (PSRPSIIRI 954-Part 4) was set up in collaboration with INTERCOVAMEX and the LOFPA laboratory whose goal is, among other things, to design and manufacture a controlled atmosphere hot draft machine for carrying out tensile tests on thin samples. The present mastery work will therefore cover the following problem: how to deform a thin sample in tension and heat it uniformly at high temperature while controlling the atmospheric conditions?
To answer this problem, a detailed functional analysis of the machine was made and a schematic diagram of the structure of the machine was proposed. A 3D model of the machine was constructed after obtaining the actual dimensions of each of the component parts of the machine, and numerical simulations allowed to validate the analytical design calculations performed.
The design of the machine is validated numerically. The next step will be the manufacture of the machine itself in order to adjust the missing points and make it functional.
