Atomic level bonding mechanism in steel/aluminum joints produced by cold pressure welding
(Journal article, 2019)Cold pressure welding of aluminum alloys and steels offers an attractive, cost-effective opportunity of joining the two most important structural materials. Aim of this work is to investigate the bonding mechanism between ... -
Boron trapping at dislocations in an additively manufactured polycrystalline superalloy
(Peer reviewed; Journal article, 2023)Segregation of solutes at dislocations in a nickel-based superalloy produced by laser powder bed fusion was investigated. Transmission electron microscopy has shown a high dislocation density present in the as-built ... -
Effect of Mn and cooling rates on α-, β- and δ-Al–Fe–Si intermetallic phase formation in a secondary Al–Si alloy
(Journal article; Peer reviewed, 2019)Secondary Al–Si alloys Al7.1Si(1.5-xMn)Fe(xMn)Mn with xMn = 0, 0.3, 0.375, 0.6, 0.75 at.% have been solidified with different cooling rates: 0.05 K/s, 1.4 K/s, 11.4 K/s and 200 K/s. In the ternary alloy with xMn = 0 at.%, ... -
Improving ageing kinetics and precipitation hardening in an Al-Mg-Si alloy by minor Cd addition
(Journal article; Peer reviewed, 2018)This study reports significant improvements in both the age hardening kinetics and peak hardness of an Al-Mg-Si alloy by microalloying with 0.06 at% Cd. A detailed high-angle annular dark-field scanning transmission electron ... -
Modelling and experimental validation of microstructure evolution during the cooling stage of homogenization heat treatment of Al-Mg-Si alloys
(Journal article; Peer reviewed, 2018)A CALPHAD-coupled multi-component multi-phase Kampmann–Wagner Numerical modelling framework has been adapted and coupled with a homogenization model to predict the competitive nucleation and growth of multi-sized ... -
Non-steady 3D dendrite tip growth under diffusive and weakly convective conditions.
(Journal article; Peer reviewed, 2019)Three dimensional α-Al dendrite tip growth under varying solute gradients in an Al-Cu-Si alloy melt has been studied using real time synchrotron X-ray imaging and mathematical modelling. X-radiographic image sequences with ... -
Precipitation and strengthening modeling for disk-shaped particles in aluminum alloys: Size distribution considered
(Journal article, 2018)For an ICME (Integrated Computational Material Engineering) modeling framework used for the age-hardening aluminum alloy design and heat treatment parameters optimization, it is critical to take into account the geometric ...
