Forming simulator Gleeble 3800-GTC

The Gleeble 3800-GTC from DSI is a physical forming simulator that can be used to investigate the thermomechanical deformation behaviour of materials. Tensile and compression tests with a maximum force of 200 kN at temperatures up to 1,500 °C and punch speeds up to 2,000 mm/s are possible. Thus, the Gleeble 3800-GTC is also suitable for the physical simulation of solid forming processes. In addition, a wide range of different sample sizes and geometries can be used. Conductive heating of the samples allows heating speeds of up to 10,000 K/s to be realised. In addition, controlled cooling by liquid or gaseous cooling media, with cooling rates of up to 10,000 K/s, is possible. In combination with the precise measuring method of a dilatometer, phase transformations of metals can thus be analysed.

In addition, the 35050 torsion unit is available at IFUM for the Gleeble. This allows materials to be tested under torsional loads of up to 112 Nm with superimposed tensile or compressive loads in the range of ± 5 kN at a maximum speed of 1,500 rpm. Here, too, thermo-mechanical treatment of the specimens can take place via controlled conductive heating or cooling by liquid or gaseous media.
