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 ...
Fracture behavior of ultrafine-grained titanium under tension at elevated temperatures
(ASME, 2020-10-01)
This investigation focused on the deformation response and microstructural changes of severely deformed titanium during post-severe plastic deformation tension, at temperatures of 300–600 °C and at strain rates of 0.001–0.1 ...
On the high-temperature flow response of friction stir processed magnesium metal matrix composites
(ASME, 2021-01-01)
In the current work, multi-pass friction stir processing (FSP) was utilized to fabricate samples of fine-grained aluminum-zinc (AZ) magnesium alloy and its metal matrix composite (MMC). The microstructure and high-temperature ...
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 ...
Low-cycle fatigue behavior of friction stir-welded copper joints
(Springer, 2021-11)
Investigation of the fatigue response of friction stir-welded (FSWed) joints is especially important in the design and manufacturing of components with exposure to cyclic loading. In this study, cyclic response of FSWed ...
Fabrication and mechanical characterization of polypropylene clay nanocomposites
(Trans Tech Publications Ltd, 2021)
Investigating the influence of process parameters is vital to enhance the mechanical properties of nanoparticle reinforced polymer composites. Nanocomposites of polypropylene/nanoclay are prepared by the extrusion method. ...
On the development of a novel multi-phase high entropy alloy with transformation-induced plasticity effect
(Elsevier, 2022-06-05)
In the present work, microstructural evolution, and mechanical behavior of a novel high entropy alloy (HEA) are investigated through thermo-mechanical processing. The homogenized samples possess a single-phase cubic structure ...
Effect of boronizing and WC coating on the high temperature mechanical behavior of AISI 321 stainless steel
(Trans Tech Publications Ltd, 2022)
In the current paper, the effect of two different coating techniques of boronizing and tungsten carbide (WC) coating on the room and high temperature tensile behavior of the AISI 321 stainless steel were investigated. ...
Advanced surface enhancement of a high strength aluminum alloy through friction stir processing
(Springer, 2022)
The current study investigates the effect of severe plastic deformation (SPD) on the mechanical behavior of a commercial aluminum alloy (Al7075). In-process cooled friction stir processing (FSP) was used to enhance the ...
