Instron, a leading provider of testing equipment designed to evaluate mechanical properties of materials and components, introduces its 8862 thermo-mechanical fatigue (TMF) systems. Designed to simulate the combined effects of thermal cycling and mechanical fatigue, Instron's TMF systems are ideally suited for the aerospace and power generation industries. These fully integrated TMF systems test materials used in gas and jet turbines to ensure that they can withstand arduous operating conditions such as emergency shutdowns and afterburner activation.

Instron's uniquely engineered 8862 has a 100 kN high-stiffness, precision-aligned load frame and a single ballscrew 100 kN electromechanical actuator. This combination provides a superior testing system designed for both low cycle fatigue and slow strain rate testing. To simulate testing in extreme heat followed by rapid cooling, Instron TMF systems feature an induction heater capable of producing ramp rates in the order of around 50°/s, as well as water-cooled hydraulic grips.

The 8862 utilizes Instron's FastTrack 8800 Controller, which provides the accurate control needed for complex TMF testing. The system is controlled using Instron's FastTrack TMF software package, which can automatically compensate for thermal strain.
