Following a recent SAFRAN audit, Exova’s laboratory in Toulouse, France, has received a new Qualification from SAFRAN for powder testing. The Toulouse laboratory is the first independent laboratory in the world to receive such a qualification on powders characterisation for Additive Layer Manufacturing (ALM) and 3D printing. This extends laboratory's wide scope of accreditations with four new test methods:
- Flow properties - ISO 4490
- Apparent density - ISO 3923-1 / EN 23923-1
- Tapped density - ISO 3953
- Laser process Granulometry - ASTM B822 / ISO 13320
The site is already qualified for scanning electron microscope (SEM) observation and will soon offer sieve test according to ASTM B214 and ISO 3310-1. This accreditation demonstrates Exova’s position as a leader in this advanced technology, supporting the global aerospace industry.
Our globally positioned experts specialise in strain and load controlledfatigue testing at low and high frequencies, crack propagation and fracture toughness of airframe and aircraft engine components and material.
Our facilities also offer a comprehensive suite of tests for the fatigue testingof non-metallic composite materials to the aerospace, automotive and power generation sectors.
We hold Nadcap Metallic, Nadcap Non-metallic and COFRAC ISO 17025 accreditation. In addition we have customer-specific approvals from Airbus, Group Safran, GE Aviation, MTU and Bombardier.
Fatigue testing (either High Cycle Fatigue or Low Cycle Fatigue) is carried out using servo-hydraulic machines. Tests can be conducted either force controlled, strain controlled or displacement controlled. Fracture toughness is an attempt to assess the effect of a notch on the basic strength of a material under a steadily increased load. Our experts are able to undertake a wide range of tests using differing geometries (K1c, J1c, Jc, R curve, crack propagation).
A range of static testing, including tensile, compression, shearing, peeling and bending, can be carried out by Exova on both metallic and composite materials.
Our specialists perform a wide range of metallographic inspections, including microscopic, macroscopic and SEM failure analysis.
- Cutting of forgings or foundry parts
- Tensile fatigue test specimens (straight or notched, cylindrical or flat), LCF etc.
- Grinding and polishing of cylindrical test specimens
- Grinding of flat test specimens
- Machining of specific tools for mechanical tests at room temperature or at high temperatures (all types of fixtures, V-notch, flat, and/or jaws, grips for CT specimens, 3 and 4 point flexure bench) and various parts (turning, drilling, boring, etc.)
- Special steels, high resistance steel (UTS<2000MPa), stainless steel, cast iron, aluminum, copper, nickel (Inconel), titanium alloys, plastic and composite materials
