Quenching and deformation dilatometer DIL 805A/D+T

Quenching and deformation dilatometer DIL 805A/D+T

The quenching and deformation dilatometer DIL 805A/D+T enables the temperature-controlled measurement of thermal and mechanical length changes and thus the investigation of phase transformations as a function of time, temperature and mechanical stress.

The inductive heating and targeted cooling enables industrial heating and heat treatment processes to be simulated.

By adding the tensile-compressive and compressive modules, specimens can be subjected to defined tensile or compressive stresses. This allows the influence of a deformation on the microstructure to be investigated and flow curves to be recorded in tensile or crush tests.

Feasible experiments and experimental parameters:

Areas of application in quenching mode:

  • Determination of the linear thermal expansion coefficient
  • Determination of structural transformations
  • Generation of time-temperature-transformation and time-temperature-austenitisation diagrams

The addition of the tension and compression insert modules allows tensile, compression and tension-compression tests to be carried out.

Areas of application in the Tension and Compression modes

  • Recording of temperature-dependent flow curves
  • Recording of structure-dependent flow curves
  • Generation of D-CCT Diagrams

Optical strain measurement

  • Extension through the self-sufficient, permanently installed ARAMIS 2D 4M system from the company GOM
  • Image resolution of 2,400 x 1,728 pixels with a frame rate of up to 168 Hz
  • Measuring lens with a focal length of 75 mm
  • Enables the recording of local strains and the determination of anisotropy parameters
