SIMET – Metallurgical Investigations Division

Activities

The laboratory activities concern traditional and innovative metallic materials. In all the studies that have been carried out, the main interest has been the correlation between microstructure (investigated by metallographic techniques) and mechanical properties (investigated by different kind of mechanical tests).

Field of interest and research are:

  • Traditional and innovative steels
  • Aluminum, Titanium and Nichel alloys
  • Wear resistant layers
  • Industrial heat treatments

Instruments

Mechanical testing machines

  • electromechanical universal testing machine for: tensile and compression tests (ambient and high temperature), and bending tests
  • electromechanical testing machine for high load-low frequency fatigue tests and fracture mechanics tests
  • hydraulic testing machines for axial fatigue tests (ambient and high temperature, at Mechanical Department in Bovisa Campus)
  • rotating bar bending fatigue tests machine
  • charpy pendulum for impact tests
  • micro and macro hardness machines
  • n°4 creep test machine array

Devices for metallographic preparation
