High-Temperature Testing Low-cycle fatigue (LCF) and other tests can be carried out at very high temperatures using furnace technologies and specialized load strings. T-Slot Table Options T-Slot base machines with the actuator in crosshead are available for testing components and structures. Thermomechanical Fatigue (TMF) Using specialized heating technologies, TMF systems simulate the combined effects of mechanical fatigue with the thermal cycling, normally experienced by gas turbines and similar equipment during operation. www.instron.com
