choose this expertise?
Looking to:
- Understand the thermal, mechanical, and metallurgical properties of your materials and/or parts.
- Develop a testing procedure and/or an original characterization device.
UBSIDE can determine thermal and mechanical properties at high temperatures as well as metallurgical characteristics. We can also adapt or design methods and devices to characterize assemblies, contacts, and thermal, mechanical, and metallurgical behaviors.
Our made-to-measure services
Characterization of properties.
Development of material behavior models.
Development of customized methods and devices.
Service Details
Thermal characterization
We can determine the thermal and electrical properties of your materials at temperatures up to 1600 °C:
- Thermal and electrical conductivity, heat capacity, density, thermal diffusivity, thermal expansion
- Thermal and electrical contact resistance (TCR/ECR)
Mechanical characterization
We determine the mechanical behavior of materials from ambient temperature up to below the material’s melting point.
- Young’s modulus, mechanical strength, Poisson’s ratio, elongation at break.
- Stress-strain curves and identification of constitutive laws.
- Forming limit curves (FLC).
Metallurgy
Using experimental simulations reproducing the thermo-mechanical cycles of your processes with the Gleeble 3500, we can replicate the metallurgy of your parts or determine thermo-mechanical cycles to achieve the targeted microstructure:
- Metallography/visual inspection,
- Hardness measurements,
- TTT and CCT diagrams,
- Heat treatments and mechanical loading.
Original devices and development of customized methods and devices
To meet specific requests or compensate for the lack of existing methods or devices to characterize properties or behaviors, our teams design original setups.
Examples of original devices:
- ECR/TCR measurement device up to 600 °C,
- ECR measurement during spot welding,
- Biaxial expansion device up to 900 °C,
- RTI (Reflectance Transformation Imaging) device for surface state characterization
Determination of properties and parameters via inverse methods
Numerical tools support the identification of your material behavior models and/or the estimation of properties through inverse methods.
Our added value
Choosing UBSIDE means benefiting from a range of expertise supported by the skills and resources of IRDL (Institut de Recherche Dupuy de Lôme). Our experts in thermal science, solid mechanics, and metallurgy guide you in selecting the most relevant properties and material behavior models to characterize, tailored to your challenges, from ambient to high temperatures.
