As a world leading supplier of integrated TMF testing solutions, Instron has systems installed in many different countries. Thermomechanical Fatigue systems can be based around the popular servohydraulic fatigue testing systems, such as the 8801 100 kN or 8802 250 kN, or can be integrated onto a 8861 or 8862 servo-electric machines. Thermomechanical Fatigue Testing systems can also be designed into more advanced systems, such as axial-torsional or planar biaxial cruciform testing machines.
The fully-automated Instron TMF testing software package complies to the relevant sections of the standards ASTM E2368 and the recently released ISO 12111. It comprises of four distinct stages:
- Stabilization
- Thermal Strain Measurement
- Verification
- TMF Testing
The latest digital RF induction heating products and forced cooling cage technology, combined with the easiness of use of the dual PID capability of the latest Eurotherm temperature controller, allow precise temperature cycling up to 1100° C with heating rates of up to and over 50° C/s and cooling rates in excess of 25° C/s.
