Brittle and Ductile Fracture of X80 Arctic Steel
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:258, Doctoral thesis, 2012)This PhD work has focused on the effect of microstructure and changes in microstructure introduced by welding procedure, on the brittle to ductile transition properties of high strength low alloy steels which have been ... -
Bubble Phenomena and Bubble Properties for Different Carbon Anodes in Cryolite Melt
(Doctoral theses at NTNU;2022:333, Doctoral thesis, 2022)This doctoral work is an experimental laboratory scale study of the effect of anode geometry, anode orientation and carbon anode material on bubble behavior and bubble properties in cryolite melt. The increased knowledge ... -
Bulk Metallic Glasses: Deformation and Design
(Doctoral theses at NTNU;2019:43, Doctoral thesis, 2019)Bulk metallic glasses are a group of alloys with amorphous atomic structure. When these alloys cool sufficiently fast, the atoms will “freeze” in the chaotic structure of the melt, rather than form crystals like most metals. ... -
