Effect of hot extrusion and T6 heat treatment on microstructure and mechanical properties of Al-10Zn-3.5Mg-2.5Cu nanocomposite reinforced with graphene nanoplatelets

Mirjavadi S.S.; Alipour M.; Hamouda A.M.S.; Kord S.; Koppad P.G.; ... more authors ... less authors ( Elsevier Ltd , 2018 , Article)

Al-10Zn-3.5Mg-2.5Cu/graphene nanocomposites were developed by a combination of liquid metallurgy and hot extrusion techniques. The effect of varying graphene content (0.1%, 0.3%, 0.7% and 1.0%) on microstructure and ...

Vibration of rotating functionally graded Timoshenko nano-beams with nonlinear thermal distribution

Azimi M.; Mirjavadi S.S.; Shafiei N.; Hamouda A.M.S.; Davari E. ( Taylor and Francis Inc. , 2018 , Article)

The vibration analysis of rotating, functionally graded Timoshenko nano-beams under an in-plane nonlinear thermal loading is studied for the first time. The formulation is based on Eringen's nonlocal elasticity theory. ...

A combined method to model dynamic recrystallization based on cellular automaton and a phenomenological (CAP) approach

Azarbarmas M.; Mirjavadi S.S.; Ghasemi A.; Hamouda A.M. ( MDPI AG , 2018 , Article)

Titanium alloys with high stacking-fault energy show continuous dynamic recrystallization (CDRX) instead of discontinuous dynamic recrystallization (DDRX) during high-temperature deformation. During the CDRX mechanism, new ...

Resonator based switching technique between ultra wide band (Uwb) and single/dual continuously tunable-notch behaviors in uwb radar for wireless vital signs monitoring

Rahman M.; Naghshvarianjahromi M.; Mirjavadi S.S.; Hamouda A.M. ( MDPI AG , 2018 , Article)

This paper presents a novel resonator that can switch and create three important behaviors within the same antenna using miniaturized capacitors. The resonator was integrated into conventional Ultra-Wide Band (UWB) antenna ...
