High Temperature Testing

High temperature testing is used across a wide range of industries to evaluate the performance, durability, and reliability of materials, components, or systems when exposed to extreme heat.

This covers a range of different test methods and temperature ranges to assess changes in mechanical properties such as tensile strength, creep resistance and thermal expansion. 

Test types include elevated temperature tensile testing, creep and fatigue testing, and thermal-elastic behaviour analysis. These tests are essential for temperature control and component validation for industries such as power, nuclear, aerospace and more. In addition to temperature testing, these tests can simulate oxidation, thermal degradation and the effect of high temperature gas environments on materials.

Core Research Programme (CRP) and Joint Industry Projects (JIP)

Core Research

Each year the TWI Core Research Programme (CRP) addresses challenges on behalf of our Industrial Members as well as developing specific technologies and processes. Each of the projects under the CRP is focussed on engineering, materials or manufacturing technologies.

Joint Industry Projects

TWI also conducts Joint Industry Projects (JIPs) that bring together groups of Industrial Members to share the cost of research activities in areas of mutual industrial interest, gaining exclusive access to the outcomes. These projects cover a broad range of topics.
