Metallic Glass Team

prof. dr hab. inż. Tadeusz Kulik
(+48) 22 234 87 19

The team is located in the Division of Structural and Functional Materials. Its members prepare metallic glasses (MGs) in the form of ribbons (15-50 μm) as well as rods and plates (1-20 mm) and also study their structure and properties. The team has been accumulating extensive experience for over 50 years, being the first in Eastern Europe to undertake and explore this topic.

Magnetic MGs are applied in magnetic cores production and flexible magnetic screens and magnetoelastic transducers. MGs are used for the production of nanocrystalline materials with very good soft magnetic properties (Fe alloys) or mechanical properties (Al alloys). MGs have a unique set of properties: they are mechanically hard and magnetically soft, they show high resistivity and good corrosion resistance.

The team is experienced in unconventional nanocrystallisation methods (high and low temperatures). At elevated temperature, bulk metallic glasses are superplastic and mouldable like polymers. They are a perfect material for hard and mirror smooth elements with a complex shape for micromechanics, e.g. micro-gears with a sub-millimeter diameter.
