Evaluation of NaOH pre-treatment on the corrosion behavior and surface characteristics of hydroxyapatite coated NiTi alloy
(Springer Nature, 2020-08-02)
Successful short-term implementation of nickel-titanium (NiTi) alloys as implants has been a motivation for the development of long-term applications. However, rendering these as safe implant materials is challenging. The ...
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 ...
Formation of nano-sized compounds during friction stir welding of Cu–Zn alloys: effect of tool composition
(Elsevier, 2020-12)
For the first time, the origin of tool composition effect on microstructure and mechanical properties of the friction stir welded joints has been disclosed. For this aim, nanoindentation, orientation image microscopy, and ...
Effect of external stress on the post-aging mechanical properties of rolled magnesium alloys
(TANGER Ltd., 2020)
In the current study the effects of conventional aging and stress aging on the microstructure and mechanical behavior of warm rolled AZ31 magnesium alloy were investigated. Tensile experiments revealed that the ultimate ...
