Mechanical properties of metallic materials

A specialised team and resources in the field of test and characterisation of metallic materials : 

• Static tensile tests to determine the mechanical properties (maximum strength, yield strength, module of elasticity, elongation, etc.), at room temperature, at high temperatures up to maximum 800°C, at low temperatures ranging to -196°C, in H2 environment.
• Impact bending tests (measurement of notch impact strength) on previously notched metallic test specimen, between ambient temperature and -196°C,
• Hardness measurements (Vickers, Brinell and Rockwell B and C)
• Flattening, bending, flaring tests,
• Tests and characterisation of many metals and alloys, either on standardised tests specimens or on products (tubes, bolts, etc.)
• Characterisation of material ageing and prediction of service life
• Characterisation of the environmental compatibility of materials

ZOOM ON HYDROGEN 

HyMEET, our technological platform dedicated to H2, provides mechanical engineering with resources and skills needed to master low-carbon hydrogen production, distribution, storage and utilization technologies. HyMEET combines an ambitious R&D program with a €25 million investment in resources dedicated to characterization and validation tests (up to 1000 bar and in a range of temperatures from deep cryogenics to high temperatures) as well as consulting and training.
 

Its activities are dedicated to:

• Characterizing the behavior of materials in contact with hydrogen
• Development of specific test methods
• Characterization of specific mechanical equipment and systems in severe hydrogen environments.

Our equipment enables:

• Mechanical characterization of materials using fatigue machines in a high-pressure hydrogen environment
• Control of sealing systems and plant containment, with test benches developed to study gas diffusion phenomena, resistance to rapid decompression and sealing performance under severe conditions
• The study of the ageing of test specimens in high-pressure autoclaves
• Tests under cryogenic conditions for the use of hydrogen in liquid form, with several cryostats fed by a helium-hydrogen liquefier
• Multiphysics tests with pressure, temperature and .... cycling.
• Manufacture of thermoplastic composite parts (tanks, tubes) by in-situ deposition and consolidation (in real time, with no further steps required) using our HySPIDE TP robotized cell.

Our specific services in the H2 environment:

• Mechanical characterisation of materials in a hydrogen environment (high pressure, gas mixtures and wide temperature range)
• Wide range of mechanical Fracture tests in H2 environments
• Support in selecting and choosing compatible materials for H2 applications
