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 ...
Fatigue characteristics of continuous welded rails and the effect of residual stress on fatigue-ratchetting interaction
(Taylor & Francis, 2020-03-16)
The importance of ratchetting-fatigue interaction is garnering interest due to complex failure mechanism of rail welds under cyclic loading. The objective of this paper is to investigate the fatigue characteristics of ...
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 ...
Influence of heat treatment parameters on the functional behavior and corrosion performance of a shape memory wire actuator
(Trans Tech Publications Ltd, 2020-04)
In the present study, the effect of heat treatment parameters on the functional response, corrosion behavior and microstructural evolution of NiTi shape memory alloys were investigated. Various heat treatment regimes were ...
Effect of coating method on the surface characteristics of niti shape memory alloy
(Trans Tech Publications Ltd, 2020)
Metallic materials including stainless steel, cobalt-chromium alloys, titanium and its alloys, and nickel-titanium (NiTi) shape memory alloys have been used in biomedical applications since the 1940s due to their favorable ...
Evaluating the mechanical behavior of ARB processed aluminum composites using shear punch testing
(Trans Tech Publications Ltd, 2020)
Multi-layered metal composites have received considerable attention due to their improved mechanical and physical properties. In this study, Al6061/Al2024 composite was processed by accumulative roll bonding (ARB) as a ...
