An explicit integration scheme for hypo-elastic viscoplastic crystal plasticity
(Journal article; Peer reviewed, 2014)An explicit integration scheme for rate-dependent crystal plasticity (CP) has been developed in this work. Additive decomposition of the velocity gradient tensor into lattice and plastic parts is adopted for describing the ... -
Application of EBSD technique to ultrafine grained and nanostructured materials processed by severe plastic deformation: Sample preparation, parameters optimization and analysis
(Journal article; Peer reviewed, 2012)With the help of FESEM, high resolution electron backscatter diffraction can investigate the grains/subgrains as small as a few tens of nanometers with a good angular resolution (∼0.5°). Fast development of EBSD speed (up ... -
Correlating oriented grain number density of recrystallisation in particle-containing aluminium alloys
(Journal article; Peer reviewed, 2018)The recrystallized grain structure of Al–(Mn)–Fe–Si alloys after isothermal annealing was studied by electron backscatter diffraction (EBSD) technique. Statistical correlation suggests that the frequency of forming P-oriented ... -
Deformation defects and electron irradiation effect in nanostructured Al-Mg alloy processed by severe plastic deformation
(Journal article; Peer reviewed, 2012)In order to explore the exact nature of deformation defects previously observed in nanostructured Al-Mg alloys subjected to severe plastic deformation, a more thorough examination of the radiation effect on the formation ... -
Effect of soft Bi particles on grain refinement during severe plastic deformation
(Journal article; Peer reviewed, 2017)Two aluminum alloys, Al–8Zn and Al–6Bi–8Zn were subjected to equal channel angular pressing (ECAP) up to 5 passes at room temperature. The microstructural evolution and the grain refinement behavior of these alloys were ... -
Finite element analysis of strain distribution in ZK60 Mg alloy during cyclic extrusion and compression
(Journal article; Peer reviewed, 2012)Finite element method was used to study the strain distribution in ZK60 Mg alloy during multi-pass cyclic extrusion and compression (CEC). In order to optimize the CEC processing, the effects of friction condition and die ... -
Influence of dispersoids on grain subdivision and texture evolution in aluminium alloys during cold rolling
(Journal article, 2014)Al-Mn alloys containing similar amounts of solutes but various dispersoid densities were cold rolled. The grain subdivision and micro-texture were examined by electron backscatter diffraction and orientation imaging ... -
Isothermal annealing of cold-rolled Al−Mn−Fe−Si alloy with different microchemistry states
(Journal article, 2014)Microstructural evolution of a cold-rolled Al–Mn–Fe–Si alloy during annealing was studied. Except the as-cast variant, two other different homogenizations were considered, one gave a high density of fine dispersiods providing ... -
Microstructure and texture characteristics of ZK60 Mg alloy processed by cyclic extrusion and compression
(Journal article; Peer reviewed, 2010)The microstructure and crystallographic texture characteristics of an extruded ZK60 Mg alloy subjected to cyclic extrusion and compression (CEC) up to 8 passes at 503 K were investigated. The local crystallographic texture, ... -
Recycling of automotive aluminum
(Journal article; Peer reviewed, 2010)With the global warming of concern, the secondary aluminum stream is becoming an even more important component of aluminum production and is attractive because of its economic and environmental benefits. In this work, ... -
Special nanostructures in Al-Mg alloys subjected to high pressure torsion
(Journal article; Peer reviewed, 2010)Deformation twins and stacking faults were observed in nanostructure Al-Mg alloys subjected to high pressure torsion. These observations are surprising because deformation twinnings have never been observed in their ... -
Twinnability of Al–Mg alloys: A first-principles interpretation
(Journal article; Peer reviewed, 2017)Al–Mg alloys are considered to have potentials to form twins during deformation because Mg can reduce the intrinsic stacking fault energy γISFE of Al. Nevertheless, twinning has rarely been found in Al–Mg alloys even ...
