Workshop : What is the impact of time in the design of metal parts?
Metallurgist since 1995 and graduated of Paris Institute of Judicial Expertise, Alexandre Fleurentin is a metallic materials and thermal and surface treatments expert. He benefits his experience from automotive industry, as a production engineer for the optimization of so-called "special" metallurgical processes. Alexandre was then technical manager and international expert in metallurgy, in charge of industrialization and innovation in thermochemical treatments, induction and non-destructive testing. Having developed a new approach (PUMP: Products - Use - Materials - Processes) in the automotive world, he became an expert engineer at the Technical Center for Mechanical Industries, where he worked in various fields : energy, railway, aeronautics, forging, cutting / stamping, machining, screws and bolts, and gears and transmissions. In 2004, he received the GKN Driveline Award for innovation for the integration of the low pressure carburizing process, as well as the first A3TS Innovation award in 2012 for his work on protection against high temperature carburization of refractory steels. .
In industrial environment, designing items means respecting applicable standards and specifications. Understanding physico-chemical phenomena is essential to take well calibrated normative precautions, which guarantee both technical reliability and operation financial viability. The time parameter can play a major role through the activation of the diffusional mechanisms of the atoms under stress or under the effect of the rise in temperature. A good example of this phenomenon is the desensitization to weakening by hydrogen of coated steel parts in the aim of improving corrosion resistance.
