Oxidation-Nitridation of chromium at high temperatures and its mitigation by alloying
Vendeur : Bookbot, Prague, Rébublique tchèque
Évaluation du vendeur 5 sur 5 étoiles
Softcover. Etat : Fine. Leichte Verformung / umgeknickte Seiten. This work investigates oxidation and nitridation in the binary Cr-Si system, focusing on the kinetics and thermodynamics of oxidation through a systematic approach. The oxidation and nitridation behavior of individual phases--solid-solution phase (Crss) and silicide phase (A15)--were studied separately, examining short and long-term exposure kinetics, thermodynamic stability, and post-exposure characterization of scale and subscale morphologies. Results indicate that chromium is the primary element in the oxidation process, making these alloys significant chromia formers. Notably, localized SiO2 formation plays a crucial role in reducing oxidation kinetics, with the oxidation rate of chromium decreasing dramatically with the addition of just 3 at.% Si. The A15 Cr3Si phase developed a continuous SiO2 layer during long-term exposure. In a two-phase eutectic alloy, both phases oxidized cooperatively, leading to chromium depletion and the formation of an A15 layer at the alloy-scale interface. The influence of nitrogen as an oxidant was also examined, revealing that a chromium subnitride layer grows via inward nitrogen diffusion, while Si significantly hinders nitridation. The A15 silicide remains stable under high nitrogen pressures and acts as a protective barrier. Further exploration of the ternary Cr-Ge-Si system showed that Ge stabilizes the A15 phase and maintains a fine-lamellar microstructure. This approach notably improved.
