MOST OUTSTANDING EQUIPMENT AND COMPONENTS
-
Dilatometer BÄHR DIL805L
Experimental facility for the measurement of steel transformation temperatures on heating (Ac1 and Ac3) and the measurement of the steel transformation temperatures on cooling for different cooling rates and procurement of CCT and TTT diagrams.
Experimental simulation of thermal treatments for any steel grade. -
Fatigue testing VIBROPHORE 250 kN with climatic chamber
Fatigue machine for the experimental determination of the S-N Wöhler curve of steels for a particular heat treatment condition under alternating or push-pull axial loading.
Fatigue testing can be done at different temperatures (from -20ºC to 500ºC) thanks to a climatic chamber. Further analysis of fatigue failures and root causes. -
Field Emission Electron Microscope ZEISS MERLIN equipped with EDS/EBSD microanalysis system
Scanning Electron Microscope (magnification x1000000, topographical and compositional image, EDS analysis, EBSD and automatic image analysis) for the characterization of steel samples, analysis of failures of mechanical components and technological advice and assistance on metallurgical processes and products.
-
Hot Forming Tests Machine GLEEBLE 3800C
Equipment for physical simulation of thermomechanical processes, analysis of hot and warm forgeability, assessment of steel hot ductility, forging stress-strain curves. It is suitable for the experimental simulation of hot forging and hot rolling processes and further estimation of properties in as-forged condition.
