In a short period of time a Gleeble can be changed from hot compression testing to hot torsion testing. The Gleeble computer control automatically senses when a Hot Torsion MCU is attached and reconfigures the computer and electronics for hot torsion testing. The torsion system is supplied complete and ready for hot torsion testing. The specimen is held in quick-lock collets and heated using both direct resistance heating and a high speed dynamic furnace elements with infrared pyrometer control. For Information on the use of the Hot Torsion MCU see Application Note 020 .
Temperature is controlled by an infrared pyrometer or a thermocouple depending on experiment design.
Longitudinal load cell with overload protection provides measurement of axial load on specimen Torque cell with overload protection provides accurate torque measurements during test. Axial load control provides combined stress states such as tension shear and compression shear. A torsion free coupler minimizes acceleration times. Optional quench systems can be used as in-situ quenching to accelerate cooling or to freeze microstructures of the specimen. The Gleeble Series 3 digital control and acquisition system is used to control the test and acquire the test results.
