(Peer reviewed; Journal article, 2020)Gd2Zr2O7 ceramic is considered as a potential candidate for thermal barrier coatings. Here we present hot corrosion behavior of single layer Gd2Zr2O7 (GZO), Gd2Zr2O7 + 50 wt% YbSZ (GZO/YbSZ), YSZ and double-layer ... -
Hot Deformation and Die-Quenching of 6000-Series Alloys—The Effect of Quench-Interruption Temperature
(The Minerals, Metals & Materials Series;2367-1696, Chapter; Peer reviewed, 2020)The automotive industry face demands to produce lightweight vehicles and substituting steel with aluminium is a straightforward solution. Age hardenable aluminium alloys are attractive candidates when the aim is a combination ... -
The hot spot in Al-rod extrusion investigated by FEM-analysis
(Peer reviewed; Journal article, 2019)FEM-analysis is applied to study thermo-mechanical conditions in an industrial Al-rod extrusion process using long billets as stock material. In the analysis, focus is on the conditions in the hot spot present inside the ... -
How calcium prevents precipitation hardening in Al–Mg–Si alloys
(Peer reviewed; Journal article, 2013)We have investigated the effect on precipitate microstructure and hardness upon adding small amounts of Ca to a base Al–Mg–Si alloy. The main investigative techniques were transmission and scanning electron microscopy. We ... -
A hybrid aluminium alloy and its zoo of interacting nano-precipitates
(Peer reviewed; Journal article, 2015)An alloy with aluminium as its base element is heat treated to form a multitude of precipitate phases known from different classes of industrial alloys: Al–Cu(–Mg), Al–Mg–Si–Cu, and Al–Zn–Mg. Nanometer-sized needle-shaped ... -
Hybrid molecular dynamic Monte Carlo simulation and experimental production of a multi-component Cu–Fe–Ni–Mo–W alloy
(Peer reviewed; Journal article, 2023)High-entropy alloys are a class of materials intensely studied in the last years due to their innovative properties. Their unconventional compositions and chemical structures hold promise for achieving unprecedented ... -
Hybrid Welding of 45 mm High Strength Steel Sections

Hydrodynamic investigation into a novel IC-CLC reactor concept for power production with integrated CO2 capture
(SINTEF Proceedings;1, Chapter; Conference object; Peer reviewed, 2015)This paper presents an investigation of the hydrodynamics of a new Chemical Looping Combustion (CLC) reactor concept for power generation with integrated CO2 capture. This concept consists of an internal circulating fluidized ... -
Hydroelastic response of concrete shells during impact on calm water
(Peer reviewed; Journal article, 2023)Many ocean structures located offshore are supported by large vertical concrete columns. High and steep storm waves – in the process of breaking – may induce large local slamming loads on these columns. The present work ... -
Hydroelastic response of Froude scaled stiffened steel panels exposed to design-critical wave slamming
(Peer reviewed; Journal article, 2023)Stiffened steel panels of offshore ocean structures may experience violent wave impacts which needs to be accounted for in design. The slamming pressures are often measured in scaled wave tank tests and imposed on finite ... -
Hydrogen Enhanced Fatigue Crack Growth Rates in a Ferritic Fe-3wt%Si Alloy
(Journal article; Peer reviewed, 2018)It is well known that the presence of hydrogen in ferrous materials promotes both static fracture and affect the material fatigue crack growth rates. The latter is often referred to as Hydrogen Enhanced Fatigue Crack Growth ... -
Hydrogen enhanced fatigue crack growth rates in a ferritic Fe-3 wt%Si alloy and a X70 pipeline steel
(Journal article; Peer reviewed, 2019)It is well known that ferrous materials can be damaged by absorption of hydrogen. If a sufficient quantity of hydrogen penetrates into the material, static fracture and the material's fatigue performances can be affected ... -
Hydrogen for maritime application—quality of hydrogen generated onboard ship by electrolysis of purified seawater
(Peer reviewed; Journal article, 2021)Maritime transport is investigating several options to reduce its greenhouse gases and air pollutant emissions. An experimental ship, Energy Observer, is using excess renewable energy to generate onboard hydrogen by ... -
Hydrogen from wet air and sunlight in a tandem photoelectrochemical cell
(Peer reviewed; Journal article, 2019)A solid-state photoelectrochemical (SSPEC) cell is an attractive approach for solar water splitting, especially when it comes to monolithic device design. In a SSPEC cell the electrodes distance is minimized, while the use ... -
Hydrogen Induced Vacancy Clustering and Void Formation Mechanisms at Grain Boundaries in Palladium
(Peer reviewed; Journal article, 2020)Hydrogen has a significant impact on the formation of vacancies, clusters and voids in palladium and other metals. The formation of vacancy-hydrogen complexes in bulk Pd and at Σ3 and Σ5 grain boundaries was investigated ... -
Hydrogen informed Gurson model for hydrogen embrittlement simulation
(Peer reviewed; Journal article, 2019)Hydrogen-microvoid interactions were studied via unit cell analyses with different hydrogen concentrations. The absolute failure strain decreases with hydrogen concentration, but the failure loci were found to follow the ... -
