A thermodynamic database for the Al-Co-Cr-Ni system is built via Calphad method by extrapolating re-assessed ternary subsystems. minimum number of quaternary parameters are included, which optimized using experimental phase equilibrium data obtained electron probe micro-analysis and x-ray diffraction analysis NiCoCrAlY alloys spanning a wide compositional range, after annealing at 900 °C, 1100 °C 1200 water quenching. These temperatures relevant to oxidation corrosion resistant MCrAlY...
The phase relations and thermodynamic properties of the condensed Al-Co-Cr ternary alloy system are investigated using first-principles calculations based on density functional theory (DFT) phase-equilibria experiments that led to X-ray diffraction (XRD) electron probe micro-analysis (EPMA) measurements. A description is developed by means diagrams (CALPHAD) method experimental computational data from present work literature. Emphasis placed modeling bcc-A2, B2, fcc-γ, tetragonal-σ phases in...
Abstract The role of nitrogen in the oxidation Ti-2W, Ti-10Al-2W (at.%) and Ti6242S was investigated using experiments air Ar-20%O 2 , two-stage where reaction gas switched from one mixture to other. When switching air, rates first increased during a short period, then decreased. This surge mass gain following introduction attributed N pickup, forming nitride layer N-enriched zone alloy, below oxide layer. subsequent decrease rate formation and/or N-rich zone, which both act as diffusion...
