Effect of temperature on the healing capacity and mechanical properties of Ti2AlC MAX phase ceramicsSuh, Minji (author), Lee, Dong Heon (author), Sloof, W.G. (author), Lee, Kee Sung (author)In this study, the self-healing capacity of Titanium Aluminum Carbide (Ti<sub>2</sub>AlC, MAX phase) was investigated. Bulk coin samples were fabricated to evaluate the self-healing capacity at different temperatures (1000, 1200, and 1400°C). The extensive self-healing capacity of Ti<sub>2</sub>AlC was confirmed on larger quasiplastic damage ...journal article 2024

Flessati, L. (author), Vecchia, Gabriele Della (author), Musso, Guido (author)Cement-bentonite cut-off walls are commonly employed in geoenvironmental applications to limit ground water flow and pollutant transport. The wide diffusion of this artificial material in the current practice is not only due to its low permeability, but also to its simplicity of use. In this paper, experimental evidences about the role of...journal article 2023
