The TMF Subsystem is ideal for inducing thermal cycling in a metallic (magnetically susceptible) specimen. A combination of induction heating and air cooling allows thermomechanical fatigue tests to be performed in or out of phase with a load force. The TMF subsystem has a user-friendly design that helps operators perform repeatable test setup tasks quickly. Air cooling jets and the induction coil have easy, repeatable adjustments, meaning that specimen changes do not require as much setup time to reestablish the initial conditions. A specimen centering tool provides quick initial position for the coil. The coil is mounted on an x, y, z positioner that has manual adjustment knobs with numerical indicators allowing 50 mm of travel in 3-axes for fine positioning relative to the specimen. A quick release slide allows the coil to be easily pulled from the test space with the ability to return to its original position. Air cooling jets are also easily folded back or removed to gain access to the specimen with the same ability to snap back into the original position.

The induction coil is coated in electrically insulating material to provide an additional safety factor against electric shock. The coil, generator and RF oscillator are water cooled and interlocked for water flow. A second interlock specimen thermocouple also provides indication in the event that the primary control thermocouple becomes detached. TestSuite software templates for TMF include test setup, to establish thermal gradients; and test run, to perform and report results on the TMF test.

THERMOMECHANICAL FATIGUE (TMF) SUBSYSTEM BROCHURE

MTS TESTSUITE FATIGUE _ FRACTURE BROCHURE

MTS Model 653 High-Temperature Furnaces are ideal for a wide variety of high-temperature tests, including tension, compression, bend and fatigue testing of metals, composites, ceramics and many other materials. The furnaces have a user-friendly design that helps operators perform setup tasks more quickly – without compromising test quality or accuracy.

Model 653 furnaces streamline test setup and specimen changeover with a clamshell design that allows operators to work from the front of the furnace at all times. This design also improves furnace alignment, which is critical to achieving proper gradients. The durable, low-maintenance insulation for Model 653.03 and 653.04 furnaces comes pre-cut, so there is no need to handle the material in the lab. It fits tighter around the pushrods, reducing heat loss and eliminating the need for wool. The flow switches of the grip water cooling circuit can be integrated with the Model 409 temperature controller, shutting down the furnace to protect the equipment and specimen in the event of a water supply failure.

Model 653.XX Furnace Features

• Capable of achieving temperatures 1000°C (1832°F) in validated testing conditions
• Single or multiple zone heating
• Clamshell design streamlines test setup, furnace alignment, and specimen changeover
• Silicon carbide heating elements and alumina fiber insulation system for low heat loss and long life
• Multiple furnace heights to accommodate diverse test requirements
• Mounting bracket for a variety of MTS load frames is included
• Designed to accommodate MTS high-temperature axial extensometers

Model 409.83 Temperature Controller Features

• Multiple mounting options - on included furnace mounting bracket or optional stand for floor or table
• Compact, ergonomic design
• Multiple level, self-tuning PID control
• SCR power relays included
• Digital communications available.
