Journal ArticleDOI
Effect of deformation temperature on mechanical properties of ultrafine grained Al–Mg alloys processed by rolling
TL;DR: In this article, an aluminum-magnesium (Al 5083) alloy was subjected to cryorolling and warm rolling followed by warm rolling in order to investigate the changes in mechanical behavior and microstructure evolution.
Journal ArticleDOI
Microstructures and impact toughness behavior of Al 5083 alloy processed by cryorolling and afterwards annealing
TL;DR: In this article, the influence of rolling at liquid nitrogen temperature and annealing on the microstructure and mechanical properties of Al 5083 alloy was studied, and it was observed that increasing the percentage of reduction of samples during cryorolling has significant effect on decreasing impact toughness at all temperatures by increasing yield strength and decreasing ductility.
Journal ArticleDOI
Effect of annealing on microstructure and mechanical properties of Al 6061 alloy processed by cryorolling
TL;DR: In this paper, an ultrafine grained structure developed in precipitation hardenable Al alloys through cryorolling by suppression of dynamic recovery followed by low temperature aging has received great research interest because of its high strength and very good ductility.
Journal ArticleDOI
Effect of ageing on tensile behavior of ultrafine grained Al 6061 alloy
TL;DR: In this paper, the ageing behavior of ultrafine grained (UFG) Al 6061 alloy, processed through multi-directional forging (MDF) at cryogenic temperature was investigated.
Journal ArticleDOI
Multi-objective optimization of process parameters of Fused Deposition Modeling (FDM) for printing Polylactic Acid (PLA) polymer components
TL;DR: In this paper, a multi-objective optimization paradigm to optimize process parameters of FDM for printing of polylactic acid (PLA) components is presented, which includes 3D CAD model, surface roughness, printing time and material length consumed.
