Characterization of a Gas Tungsten Arc Welding (GTAW) joint of Armco iron nanostructured by equal-channel angular pressing (ECAP)
(2021-02)
Article
Accés obertAfter Severe Plastic Deformation (SPD), the strength of the Armco iron sharply increases with the number of Equal-Channel Angular Pressing (ECAP) passes. So, the ultimate tensile stress (UTS) reached up to 800¿MPa after ... -
Corrosion-induced damage and residual strength of WC-Co,Ni cemented carbides: influence of microstructure and corrosion medium
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-19)
Article
Accés obertThe corrosion behavior of cemented carbides with binders of different chemical nature (Co and Ni) and carbides with distinct mean grain size (ultrafine and coarse) was studied. The investigation also included corrosion ... -
Deformation mechanisms of metastable stainless steels accessed locally by monotonic and cyclic nanoindentation
(Universitat Politècnica de Catalunya, 2016-07-21)
Tesi
Accés obert
Realitzat a/amb: Université de LorraineMetastable austenitic stainless steels feature an abundance of different deformation mechanisms, which contribute to the distinguished mechanical properties of these alloys. However, these properties are known to depend ... -
Effect of loading mode on the microstructural heterogeneity of ultra-fine-grained iron
(2021-12-01)
Article
Accés obertThis manuscript analyzes the microstructural changes introduced by both monotonic tensile and cyclic loads in ultrafine-grained Armco iron obtained after severe plastic deformation by equal channel angular pressing. The ... -
Effect of microstructural heterogeneity on the balanced-biaxial and tensile behavior of a Zn alloy sheet
(Elsevier, 2022-03)
Article
Accés obertA 0.65 mm thick Zn sheet was processed at room temperature by equal channel angular sheet extrusion (ECASE), which allowed for the fabrication of a heterogeneous material. The processed sheet's heterogeneity manifested as ... -
Emerging organic contaminants in vertical subsurface flow constructed wetlands : Influence of media size, loading frequency and use of active aeration
(2014-10-01)
Article
Accés restringit per política de l'editorialFour side-by-side pilot-scale vertical flow (VF) constructed wetlands of different designs were evaluated for the removal of eight widely used emerging organic contaminants from municipal wastewater (i.e. ibuprofen, ... -
Heterogeneity consequences on the mechanical and microstructural evolution of an AlSi11Cu alloy obtained by selective laser melting
(2021-04)
Article
Accés obertAn AlSi11Cu alloy was obtained by additive manufacturing (AM) using powder bed fusion by selective laser melting (SLM) from powders with a mean particle size of 40 µm. The printed alloy presented abnormal melting pools ... -
Heterogeneity of strain path, texture and microstructure evolution of AA6063-T6 processed by Equal Channel Angular Sheet Extrusion (ECASE)
(2018-11)
Article
Accés obertAn Aluminum alloy 6063T6 was processed at room temperature by Equal Channel Angular Sheet Extrusion (ECASE). Microstructure evolution was investigated by Electron Back Scattering Diffraction (EBSD), and X-ray diffraction ... -
Inducing heterogeneity in an austenitic stainless steel by equal channel angular sheet extrusion (ECASE)
(Elsevier, 2019-04)
Article
Accés obertAn austenitic stainless steel was processed at room temperature by equal channel angular sheet extrusion (ECASE). The microstructure evolution was heterogeneous across the sheet thickness with a higher martensitic ... -
Microstructural and mechanical study in the plastic zone of ARMCO iron processed by ECAP
(2017-06-14)
Article
Accés obertPlastic deformation of ARMCO iron processed by ECAP up to a maximum equivalent strain of sixteen (i.e., 1, 4, 8, and 16 ECAP passes) following route Bc was investigated by analyzing its microstructure and the stress-strain ... -
Neural network modelling of Abbott-Firestone roughness parameters in honing processes
(2017-12-29)
Article
Accés obertIn present study, three roughness parameters defined in the Abbott-Firestone or bearing area curve, Rk, Rpk and Rvk, were modelled for rough honing processes by means of artificial neural networks (ANN). Input variables ... -
Surface microstructural changes of spark plasma sintered zirconia after grinding and annealing
(2016-11-01)
Article
Accés obertSpark plasma sintered zirconia (3Y-TZP) specimens have been produced of 140 nm 372 nm and 753 nm grain sizes by sintering at 1250 °C, 1450 °C and 1600 °C, respectively. The sintered zirconia specimens were grinded using a ...
