Abstract:
Determination of corrosion rate by means of electrochemical methods such as polarization resistance is limited to open-circuit conditions. In the case of cathodic protection, a protected object is polarized to protection potential by means of negative total current, the value of which is thus useless for quantifying corrosion rate. [..]

Abstract:
The plasma nitriding is a process of thermo-chemical treatment using direct-current glow discharge to improve elemental content of nitrogen to the surface of steel for subsequent diffusion into the bulk of material. An ambient atmosphere was consisted of mixture of nitrogen and hydrogen; temperature should be between 480 and 560 °C. [..]

Abstract:
High entropy alloy AlCoCrFeNiTi0.5 was produced by a combination of mechanical alloying (MA) and spark plasma sintering (SPS) processes. In our study we have investigated the effect of four different sintering temperatures (ranging from 1150 to 1300 ºC) on microstructures and phase composition of sintered samples by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and Vickers microhardness tests.

Abstract:
Severe plastic deformation methods preserve dimensions of the material and reduce the grain size down to submicrometer scale. Twin-roll cast strips prepared from AA 3003 aluminum alloy (in wt.%) with 1 % Mn, 0.2 % Fe, 0.5 % Si, 0.2 % Cu and small additions of zirconium (0.2 %) and chromium (0.1 %) were subjected to deformation by Constrained Groove Pressing (CGP).

Abstract:
Existing exact knowledge on fatigue crack growth parameters and characteristics is an essential condition for an application of Damage Tolerance design philosophy in dynamically loaded structures. Measurement of fatigue crack growth (FCG) rates in an Al 7175-T7351 alloy of a particularly high homogeneity was carried out as a part of the Proficiency Test Programme organised by Exova in France.
