A physically-based constitutive model applied to AA6082 aluminium alloy at large strains, high strain rates and elevated temperatures
(Journal article; Peer reviewed, 2016)This paper presents a physically-based constitutive model applied to an AA6082 aluminium alloy subjected to large strains, high strain rates and elevated temperatures. The model accounts for thermo-elasticity, thermo-vis ... -
Achieving superior dispersion-strengthening effect in an AA5xxx Al-Mg-Mn alloy by mico-alloying
(Peer reviewed; Journal article, 2023)5xxx Al-Mg based alloys are widely applied as non-heat-treatable alloys. In this work, we designed a dispersion-strengthening Al-4Mg-1Mn-0.3Fe-0.2Si-0.2Zr-0.2Cr (wt.%) alloy. By applying ramp heating and 400 °C isothermal ... -
Impurity removal from Si by Si-Ca-Mg ternary alloying-leaching system
(Peer reviewed; Journal article, 2020)In this work, Si-Ca-Mg alloys were made with different compositions and solidification conditions to investigate the impurity segregation and separation performance from Si, especially for the crucial P impurity at several ... -
Layer continuity in accumulative roll bonding of dissimilar material combinations
(Journal article; Peer reviewed, 2013)Strips were made by accumulative roll bonding of up to 64 alternating layers of an AA3103 alloy and either commercial purity copper or CuZn20 brass as the second type of layer. With increasing number of accumulative roll ... -
Nanoparticle additions promote outstanding fracture toughness and fatigue strength in a cast Al–Cu alloy
(Peer reviewed; Journal article, 2020)Fatigue resistance and fracture toughness are essential to the reliability of castings during service. Reducing microporosity in cast alloys is a crucial issue for improving their fatigue strength and fracture toughness. ... -
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 ... -
The effect of heavy deformation on the precipitation in an Al-1.3Cu-1.0Mg-0.4Si wt.% alloy
(Journal article; Peer reviewed, 2020)This work has investigated the effect of the combination of natural ageing and 80% pre-deformation after solution heat treatment on precipitation during subsequent artificial ageing in an Al-1.3Cu-1.0Mg-0.4Si wt.% alloy. ...
