Hot Torsion Mobile Conversion Unit

Hot Torsion with High-Speed Thermal Capacity

Features Include:

• Rapid, uniform direct resistance heating of samples
• Heating of test specimens at any time during torsion
• Rapid in-situ quenching of the test specimen at any point in the test (DR heating only)
• Use air, water or mist for quench media
• Apply controlled tension axially during torsion
• Torsion tests can be conducted with full axial restraint or no axial restraint
• High-speed hydraulic torque motor for rapid strain rate changes
• Variable torsion coupler for higher acceleration speeds
• Free coupler minimizes strain error during specimen loading
• Optional specimen furnace available

Key Performance Specifications: 

• Tests may be performed in vacuum (10-2 torr), inert gas or air (Atmosphere tank is included, vacuum pumps are optional)
• Temperature is controlled by a thermocouple attached to the fixed end of the specimen.
• Specimen size:
  • Gage length diameter: 6 mm to 10 mm diameter
  • Gage length: 6mm to 50 mm
• 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 Control and Data Acquisition System is used to control the test and acquire test results. All software is Windows based. Variables include:
  • Temperature program
  • Actual specimen temperature (multiple channels)
  • Axial force on specimen
