An experimental and theoretical analysis of vapor-to-liquid phase change on microstructured surfaces
(Elsevier, 2020-09)
In this work, an experimental and a theoretical study was carried out on condensation heat transfer on vertically aligned bare unstructured, micro V-grooved and square-grooved copper substrates. During the experiments, ...
Effect of commercial purity levels on the mechanical properties of ultrafine-grained titanium
(Elsevier, 2011-03-15)
Two grades of commercial purity (CP) titanium (grades 2 and 4) were processed using equal-channel angular extrusion (ECAE) at 300 ◦C and 450 ◦C, respectively. The processing temperatures were the minimum temperatures at ...
Simultaneous improvement in strength and ductility of severely deformed niobium alloy
(Elsevier, 2020-11-15)
The present study is on the improved monotonic response of a severely deformed niobium-based alloy. Nb-1Zr alloy was processed at room temperature using equal channel angular extrusion and cold rolling. After 16 passes, a ...
Hardness and wear resistance of roller burnished 316L stainless steel
(Elsevier, 2021)
This study investigates the effects of roller burnishing on the microstructure, surface microhardness, and wear resistance of 316L stainless steel. Experimental design based on the Taguchi orthogonal array was employed to ...
Severe plastic deformation as a processing tool for strengthening of additive manufactured alloys
(Elsevier, 2021-08)
For the first time, the novel combination of multi-pass equal channel angular extrusion/pressing (ECAE/P) and selective laser melting (SLM) was investigated. Herein, four passes of ECAP via route Bc at 150 °C were applied ...
Effect of a multi-phase structure on the damping response of a novel high entropy alloy
(Elsevier, 2022-12-01)
In this study, dynamic behavior of a novel multi-phase high entropy alloy (HEA) was investigated. Thermo-mechanical processes containing an 80 % thickness reduction at room temperature rolling followed by annealing at 750 ...
On the low-cycle fatigue behavior of a multi-phase high entropy alloy with enhanced plasticity
(Elsevier, 2023-08)
A multi-phase non-equiatomic FeCrNiMnCo high entropy alloy (HEA) was fabricated using vacuum induction melting. Thermo-mechanical treatments consisting of cold rolling and annealing at 750 °C and 850 °C were employed to ...
Effect of friction stir processing on the fatigue performance of AZ31 magnesium alloy
(Wiley, 2023-05)
Herein, the cyclic mechanical behavior of AZ31 magnesium alloy after multipass friction stir processing (FSP) is investigated up to the very high-cycle fatigue (VHCF) regime. The grain refinement and texture evolution after ...
