High temperature flow response modeling of ultra-fine grained titanium
(MDPI AG, 2015)
This work presents the mechanical behavior modeling of commercial purity titanium subjected to severe plastic deformation (SPD) during post-SPD compression, at temperatures of 600-900 °C and at strain rates of 0.001-0.1 ...
Effect of severe plastic deformation on the damping behavior of titanium
(Elsevier, 2019-06-01)
In this work, influence of severe plastic deformation on the damping properties of commercial purity titanium is explored. Deformation induced grain refinement improved the strength at room temperature while this effect ...
Effect of purity levels on the high-temperature deformation characteristics of severely deformed titanium
(Springer International Publishing, 2017)
In the present investigation, high-temperature compression tests were conducted at strain rates of 0.001 to 0.1 s−1 and at temperatures of 873 K to 1173 K (600 °C to 900 °C) in order to study the hot deformation characteristics ...
On the mechanical behavior of cold deformed aluminum 7075 alloy at elevated temperatures
(Elsevier, 2016-07-18)
In the present study, elevated temperature deformation behavior and microstructural evolution of 7075 aluminum alloy at annealed and cold rolled conditions were examined. Isothermal uniaxial tensile tests at a temperature ...
Optimization of the intermediate layer friction stir spot welding process
(Springer Nature, 2019-09)
Friction stir spot welding was performed for joining sheets of 2024 and 6061 aluminum alloys, which is otherwise difficult using conventional welding techniques. The presented approach utilizes an intermediate layer to ...
Development of an antagonistically actuated smart joint
(Trans Tech Publications, 2017)
Shape memory alloys with their phase transformation properties; have been broadly implemented in smart structures. In this study, a functional design is presented where two wires actuate antagonistically to achieve motion ...
Discrete-time integral sliding mode control of a smart joint for minimally invasive surgeries
(IEEE, 2016)
In this work, a shape memory alloy(SMA) actuator based joint (smart joint) is controlled using a discrete-time integral sliding mode (DISM) control to guide the motion of an active catheter. Controller is designed on the ...
On the mechanical behavior of accumulative roll bonded lightweight composite
(IOP Publishing, 2019-09)
Multi-layered composites have received great interest due to their enhanced mechanical and physical properties. In this study, Al6061/Al2024 composites were processed by accumulative roll bonding as a severe plastic ...
High temperature characteristics of Al2024/SiC metal matrix composite fabricated by friction stir processing
(Elsevier, 2018-07-25)
In the present study, friction stir processing (FSP) is used for the synthesis of an aluminum metal matrix composite (MMC) reinforced by SiC particles. MMC specimens with reinforced microstructures exhibited significant ...
Influence of warm rolling and aging on the microstructural evolution and mechanical behavior of AZ31 magnesium alloy
(American Institute of Physics Inc., 2019)
The microstructural evolution and tensile properties of AZ31 after warm rolling and different aging methods and conditions were investigated. The warm rolling was conducted on the as-received AZ31 after homogenization at ...
