Purpose of equipment:

• The device is capable of producing thin (below 100μm) and narrow (2-3 mm) strips of different metals and alloys from the melt by cooling speeds 105 to 106 K / s. In this way, the hardened alloy has a chemical composition, microstructure and properties that differ significantly from those conventionally made from metallic materials. Some materials are also made for research institutions from abroad (sources of energy, materials, shape memory).

• Phase and chemical composition (EDS)
• SEM JEOL-5610 is intended for the surface analysis of solids in vacuo 10-5do 10-6 mbar. It is equipped with an energy dispersive X-ray spectrometer that allows for a qualitative and quantitative chemical microanalysis, a sensor for back scattered electrons (enable phase analysis) and a sensor for secondary electrons (indicates a relief surface and thereby detects the microstructure of the analysed material). It is used in the development and testing of materials, supporting technologies, analysis of injuries and forensic research.

Purpose of equipment:

• Simultaneous thermal analysis (STA) is a method of thermal analysis that makes it possible to investigate a variety of samples by two or three thermal-analytical methods. Usually those are thermogravimetry (TG), differential thermal analysis (DTA) and differential scanning calorimetry (DSC). Simultaneously, the investigation can be done on processes based on energy difference (absorbing and relaxing heat under reaction) and investigation of mass change (oxidation, degradation, etc.). STA measurement is a complex measurement that is recommended for determining the physical – chemical properties of materials, especially new ones. Simultaneously, the modelling of technological processes can be done. STA analysis makes it possible to determine characteristic temperatures (melting point, boiling point, allotropic modifications, etc.), thermal effect (melting / solidification enthalpy, combustion heat, etc.), specific heat Cp, loss or increment of mass, etc.

Purpose of equipment:

• In order to monitor coagulation and formation of microstructures, a conical measuring cell for “in situ” simple thermal analysis has been developed. The measurement cell is made of grey cast iron with lamellar graphite. It is cone-shaped and enables the production of castings in which it is possible to keep track of coagulation by thermal analysis as a function of continuously changing the cooling rate.

Purpose of equipment:

• The tensile machine, with a work area of up to 250 kN, in addition to the standard equipment is supplemented by a stove that provides testing at a hot temperature of up to 700 °C. Triple temperature control in the oven allows the execution of complex measurements such as the determination of Superplastic properties of metallic materials.
