Lecture

MAX-phase (Ti2AlC) foams by gelcasting

Thursday (25.10.2018)
09:50 - 10:10
Part of:


Ceramic MAX-phase (Ti2AlC) foams were manufactured by gel-casting. As gelling agent agarose was used. The microstructural, mechanical and thermal properties were investigated. SEM-analysis was used for microstructural determinations and compared with X-ray micro tomography measurements. Impulse excitation technique was used for Young’s Modulus of Ti2AlC foams determination. The experimental data was correlated with the Gibson-Ashby, Spriggs and Cross-property relation models. Laser-Flash analysis were used to determine thermal conductivity up to 900°C. These measurements were correlated to the pore network in the Ti2AlC foam structure derived from μCT measurement. FEM-simulations of the mechanical behaviour were carried out on real structure models to determine a strut wise stress distribution under load.
