Temperature Control

Elevated temperature mechanical testing is a reliable process used to evaluate the behavior of metallic materials when subjected to a combination of high heat and stress/strain. High temperature tests are performed routinely in many industries for assessing material performance of metal that will be exposed to high temperatures while in service, including nickel alloys intended for jet engines and power generation gas turbines.

The majority of test frames at SMaRT are fitted with a furnace for high temperature operation. Accurate temperature control is critical for delivering high quality testing in compliance with the required test standards.

Typically, three zone cylindrical resistance furnaces are fitted to creep frames, whilst a split design cylindrical furnace is used on the universal test frames, to facilitate loading. These furnaces operate up to temperatures around 1000°C.

Additionally, SMaRT has a number of smaller split box furnaces capable of temperatures of 1300°C, which are also useful for applying accurate temperature control to a small test section.

A limited number of machines are equipped with induction heating systems which can apply a very precise heat affected zone. These are primarilty used for thermo-mechnical fatigue testing.

SMaRT also has a suite of bench mounted furnaces for heat treatment of specimens . Furnace conditions close to the specimens are monitored with type N thermocouples connected to digital displays.
