Precipitation in a mixed Al-Cu-Mg/Al-Zn-Mg alloy system
(Journal article, 2016)The precipitation-hardened alloy systems Al–Cu–Mg (2xxx) and Al–Zn–Mg (7xxx) were compositionally combined from a base alloy containing 2% Cu and 1% Mg, added 1–4% Zn (weight fractions). Precipitates in these alloys were ... -
Precipitation in an A356 foundry alloy with Cu additions - A transmission electron microscopy study
(Journal article; Peer reviewed, 2019)The influence of different Cu addition levels on the age hardening and precipitation behaviors in an Al356 foundry alloy during artificial aging treatment has been systematically studied. A detailed characterization of the ... -
Precipitation in an Al-Mg-Cu alloy and the effect of a low amount of Ag
(Journal article, 2016)Two high-purity aluminium alloys based on composition Al–3.0Mg–1.0Cu (wt%), one with added 0.4 wt% Ag, were compared up to 11 days ageing at 443 K by means of transmission electron microscopy and hardness measurements. The ... -
Precipitation in an extruded AA7003 aluminium alloy: Observations of 6xxx-type hardening phases
(Journal article; Peer reviewed, 2019)Precipitation behaviour in an industrially extruded AA7003 alloy has been studied using Transmission Electron Microscopy (TEM) together with Differential Scanning Calorimetry (DSC). Air Cooling (AC) after solution heat ... -
Precipitation of Non-Spherical Particles in Aluminum Alloys Part I: Generalization of the Kampmann–Wagner Numerical Model
(Journal article, 2015)Particles precipitated during aging treatments often have non-spherical shapes, e.g., needles or plates, while in the classical Kampmann–Wagner Numerical (KWN) precipitation model, it is assumed that the particles are of ... -
Precipitation of silver particles with controlled morphologies from aqueous solutions
(Journal article; Peer reviewed, 2019)Synthesis of silver particles with controlled morphologies enables their use in a variety of applications. Although several synthetic approaches have been developed to successfully modify the final particle shape, the ... -
Precipitation, mechanical properties and early slant ductile fracture in cyclic and naturally aged Al-Zn-Mg(-Cu) alloys
(Peer reviewed; Journal article, 2022)Natural and artificial ageing treatments are compared with ageing by cyclic deformation at room temperature. Atom probe tomography and transmission electron microscopy revealed that a fine distribution of GP-zones, was ... -
Precipitation, strength and work hardening of age hardened aluminium alloys
(Journal article; Peer reviewed, 2015)The strength and work hardening of age hardened AA6063 and AA6082 alloys have been investigated in terms of a detailed characterization of precipitate and dislocation structures obtained by TEM and SEM. Tensile and compression ... -
Precise geoid determination over Sweden using the Stokes-Helmert method and improved topographic corrections
(Peer reviewed; Journal article, 2001)Four different implementations of Stokes's formula are employed for the estimation of geoid heights over Sweden: the Vincent and Marsh (1974) model with the high-degree reference gravity field but no kernel modifications; ... -
Precision calculation of the entrance length for laminar flow of Bingham fluid between parallel plates with yield number from 0 to 1000
(Journal article; Peer reviewed, 2024)An estimate of the entrance length for a Bingham fluid flowing between parallel plates is needed in engineering applications. The dimensionless entrance length is a function of yield number. The primary objective of this ... -
Precision Deep-Stall Landing of Fixed-Wing UAVs using Nonlinear Model Predictive Control
(Peer reviewed; Journal article, 2020)To be able to recover a fixed-wing unmanned aerial vehicle (UAV) on a small space like a boat deck or a glade in the forest, a steep and precise descent is needed. One way to reduce the speed of the UAV during landing is ... -
Precision fish farming: A new framework to improve production in aquaculture
(Journal article; Peer reviewed, 2017)Aquaculture production of finfish has seen rapid growth in production volume and economic yield over the last decades, and is today a key provider of seafood. As the scale of production increases, so does the likelihood ... -
