Thermomechanical Fatigue (TMF) Testing

Thermomechanical fatigue (TMF) testing is a variant of fatigue testing designed to simulate real-world service conditions of engineered components. Specifically, TMF tests characterize the response of materials to both cyclic mechanical loading and fluctuating temperature, which produce a synergistic response that may not be well-predicted with isothermal fatigue testing. TMF tests are most frequently conducted on high-temperature alloys used in jet engines, using a combination of in-phase and out-of-phase mechanical and thermal cycling.

MTS offers a comprehensive packaged solution to address complexities of TMF testing. The solution applies thermal cycles to metallic, magnetically susceptible specimens using a combination of induction heating and air cooling. The MTS TMF Testing Solution reduces set-up times, simplifies specimen changes and increases the precision of the test data. It is specifically engineered to perform highly accurate and repeatable strain-controlled TMF testing at specimen temperatures up to 1200°C. The solution includes extremely versatile software that can read temperature and total strains measured by an extensometer, as well as calculate and control mechanical strain in real-time. Other important offerings for TMF include:

Easy access to the specimen for straightforward specimen changes
Precise and repeatable positioning of coil and air vents relative to specimen
Integrated control of the load frame, heating, and cooling using MTS TestSuite™
   software
Predefined test templates compliant with ASTM E2368 and EUR 22281
   EN standards
Repeatable induction coil manufacturing
