A műszaki leírások alapján a Bizottság úgy véli, hogy a szóban forgó intézkedések nem minősülnek állami támogatásnak, mivel a Bizottság nem tudja megállapítani, hogy a támogatás milyen mértékben befolyásolja a belső piaccal való összeegyeztethetőségét.

Youngs Modulus

Young 's modulus measures the stigness of a material. It it defined ad the ratio of stress to strain the elastic limit. For ceramics, typical valentes range from 100 to 400 GPa, depositig on composition and d microstructura.

To calculate Young 's modulus, a tensile or compression tet i performed. The slope of the initial linear portion of the stress- strain curve provides tis value.

Hardnesfélék

Hardnes indicates a material 's resistance to localized plastic deformation. It it is complily measured using indentation tests, such as Vickers or Knoop hardness tests. Higher hardness value assices inspectet better wear resistance.

Hardness can be estimated idea empirical relationships with other properties or directly measuredi in laboratory settings. Typical ceramic hardness value es range from 10 to 30 GPa.
