Biaxial strength and slow crack growth in porous alumina with silica sintering aid
Bakken, Astrid; Wagner, Susanne; Hoffmann, Michael; Einarsrud, Mari-Ann; Grande, Tor; Thorstensen, Bernt (Journal article, 2018)Biaxial strength, fracture toughness and subcritical crack growth are reported for coarse grained porous alumina ceramics. The materials were prepared with a varying amount of a silica sintering aid, which resulted in the ... -
Determining fundamental properties from diffraction: Electric field induced strain and piezoelectric coefficient
Hinterstein, Manuel; Lee, Kaiyang; Esslinger, Sophia; Glaum, Julia; Studer, Andrew; Hoffman, Mark John; Hoffmann, Michael (Peer reviewed; Journal article, 2019)Neutron powder diffraction was used in operando to determine the macroscopic strain and piezoelectric coefficient as a function of applied electric field in a technically relevant actuator material. We were able to ...
