Composition and microstructure control is the key to establishing acceptable material properties. TWI provides a comprehensive materials testing and characterisation services, with a particular emphasis on joints, which supports its Industrial Member's needs across a broad spectrum.

We provide:

• Expert, multidisciplinary interpretation of data
• Light optical microscope and scanning electron microscope (SEM) imaging to 100,000X
• Grain size, crystallographic type, orientation, phase balance and local strain analysis by electron back scattered diffraction (EBSD)
• X-ray diffraction identification of phase type and volume fraction
• Chemical analysis by optical emission spectroscopy
• Microanalysis by energy dispersive and wavelength dispersive x-ray (EDX and WDX) techniques, including an electron microprobe, for example for microphase, inclusion and surface deposit analysis
• Hydrogen analysis by vacuum hot extraction, fusion and Yanaco methods
• Carbon, sulphur, oxygen and nitrogen analysis
• Differential scanning calorimetry
• Fourier transform infrared spectrometry
• Collection and analysis of welding fume and ozone
• Hardness and microhardness measurement
