In December 2000, a laboratory for dilatometer studies was launched within the Institute of Plastic Working and Safety Engineering. The basic equipement here is a deformation dilatometer DIL805A/D. It enables determination of phase transition temperatures in a material that is being heated up and cooled down. It also generates CTPc and CTPi charts. A plastometric adaptor allows for deformation in controlled conditions.

   The device generates real work-hardening curves, thanks to which, with the use of commercial packages based on MES, it is possible to conduct numerical simulations of production of any products for actual reological properties of certain materials. The device also enables physical simulation of multistage deformations typical for modern continous mills. Moreover, there’s a possibility of physical simulations of thermomechanical treatment and modelling of microsturcture evolution through application of changeable cooling conditions after deformation. Cylinder samples are heated up with the use of induction method by means of an inductor. Such solution ensures heating up at the speed of 4000K/s. For cooling, different types of gases are applied. Thanks to utilisation of noble gas during cooling, there’s no oxide layer in the processed material.

  • Heating rate: 4000 [K/s]
  • Cooling rate: 2500 [K/s]
  • Deformation speed: 0,01 - 15 [l/s]    
  • Piston movement speed: 0,01 - 150 [mm/s]
