EXPERIMENTAL STUDY, MODELING AND NUMERICAL SIMULATION OF ALLOY 2219
Nowadays, aluminum is becoming more and more essential, in particular the alloys with structural hardening which allow a consequent lightening of the structures. As part of the simulation of heat treatment of industrial parts in aluminum alloys, models are integrated into the FORGE® software aimed at describing the hardenability and structural hardening of aluminum alloys, making it possible to simulate and predict the evolution of the mechanical properties of an industrial part subjected to complex thermal paths and check the adequacy with the customer specifications.
These models require specific material parameters and are obtained by an identification procedure based on mechanical characterizations after quenching and artificial aging of standardized specimens.
This end-of-study project will be divided into two stages.
A first experimental part located at SIMAP, in Grenoble (France) where the tasks will be as follows:
- Thermal and mechanical treatments on alloy 2219 (quenching and tempering, stress relieving), use of furnace, Jominy test
- Use of strain gradient specimen and image correlation methods.
- Mechanical (hardness, tensile tests) and microstructural characterizations to determine (DRX, SEM, DSC)
- Understanding and modeling of metallurgical phenomena (bibliographic study)
- Calibration of existing models of QFA & Shercliff-Ashby models for alloy 2219, taking into account the effect of stress relief on the final mechanical property.
- Use of FORGE® software to validate the calibration on simulations of laboratory and industrial tests (partnership with Aubert & Duval)
- Master's degree with the prospect of continuing with a CIFRE thesis.
- School with a materials / metallurgy / forming specialty
- Interest in experimental work (body of the project) and knowledge of standard treatments and tests (tensile tests, hardness, heat treatment, quenching, etc.)
- Programming basics
- Basics on numerical simulation software
- Strong interest in metallurgy and the understanding of physical phenomena
- Autonomous, rigorous, good interpersonal skills.
Approved internship for a period of 6 months from February 2022.
This internship should continue with a CIFRE Simap/Transvalor thesis which will explore the design space of 7000 series aluminum alloys. A high-throughput experimental approach (synchrotron) will thus be coupled with Machine Learning methods to develop models predictive on a wide range of alloys and thermomechanical paths.
