SiC whiskers-aluminium 6061 composite: microstructure and mechanical characteristic anisotrophy
No full textThermogravimetric investigation on oxidation kinetics of several Ti-Al alloys
No full textBars of Ti-48Al-2Cr-2Nb, Ti-48Al-2Nb-0.7Cr-0.3Si, Ti-43.5Al-4Nb-1Mo and Ti-47Al-2Cr-8Nb alloys were produced by Electron Beam Melting. The oxidation resistance in air of these alloys was investigated in the range of 800-1000 °C. Oxidation tests were performed in TGA equipment under isothermal conditions at different temperatures. The composition of the oxide layers was investigated by XRD, SEM-EDS and XPS. The oxide layers grew according to a parabolic law. The kinetic rate constants and the activation energies were calculated from the TGA results. These kinetic parameters allowed to assess a rank of oxidation resistance, which can be correlated with the composition of the alloys
