TEi has a comprehensively equipped and UKAS accredited laboratory with a team of highly qualified, trained and experienced metallurgical and technical staff operating to the requirements of an internationally acknowledged quality standard ISO/IEC 17025.
We offer a range of services including:
Ambient, elevated and sub-zero temperature tensile testing to European (BSEN) and American (ASTM) specifications. Testing can include Yield & Ultimate Strength, Elongation, Reduction of area & Proof testing. All testing is carried out using a 500kN Servo-hydraulic MAYES machine linked to an INSTRON controller.
Dedicated European and American test machines for cryogenic, ambient and elevated temperature Charpy Impact tests and Universal Test Machines for evaluation of Toughness and fracture properties (ductile and brittle behaviour).
Flexibility, Formality and Fracture properties.
Rockwell, Vickers and rebound hardness test machines for evaluation of hardness properties.
Using optical microscopes and stereoscopes Micro and Macroscopic examination of materials up to x1000 magnification is available .Scanning Electron Micrsoscopy (SEM) with magnification upto 200,000x and Energy Dispersive X-ray (EDX) spectroscopy are also available for analysis of fracture and microscopic features.
We offer characterisation of:
Pitting and Intergranular Corrosion tests can be conducted to measure the stability of materials and fitness for purpose.
We typically test to standards:
Rapid spectrographic analysis of low and high alloy steels using Optical Emission Spectrometry (OES).
Gas in metal analysis utilising Thermoconduction and Infra-red techniques.
Composition of debris, corrosion scales and other objects using Energy Dispersive X-ray (EDX) Spectroscopy.
MUFFLE FURNACES are available for heat treatment of test specimens and establishing simulated high temperature service effects on microstructure and physical properties.
We can assist with the optimisation of product heat treatment parameters and determination of hardenability.
We offer a raange of NDT solutions including:
Supplementary to the NDT techniques TEi Metallurgical Services specialises in:
