Achieving room temperature superplasticity in Zn-5Al alloy at high strain rates by equal-channel angular extrusion
Demirtas M.; Purcek G.; Yanar H.; Zhang Z.J.; Zhang Z.F. (Elsevier Ltd, 2015)Multi-pass equal-channel angular extrusion/pressing (ECAE/P) was applied to the eutectic Zn-5Al alloy to achieve high strain-rate (HSR) superplasticity in that alloy at room temperature (RT) by producing ultrafine-grained ... -
Effect of different processes on lamellar-free ultrafine grain formation, room temperature superplasticity and fracture mode of Zn-22Al alloy
Demirtas M.; Purcek G.; Yanar H.; Zhang Z.J.; Zhang Z.F. (Elsevier Ltd, 2016)The Zn-22 wt.%Al was processed using five different selected routes including thermal, thermo-mechanical and severe plastic deformation (SPD) techniques in order to produce ultrafine grained (UFG) microstructure for achieving ... -
Effect of equal-channel angular pressing on room temperature superplasticity of quasi-single phase Zn-0.3Al alloy
Demirtas M.; Purcek G.; Yanar H.; Zhang Z.J.; Zhang Z.F. (Elsevier Ltd, 2015)Quasi-single phase (dilute) Zn-0.3Al alloy was subjected to severe plastic deformation via equal-channel angular extrusion/pressing (ECAE/P), and the effects of ECAP on its room temperature (RT) and high strain rate (HSR) ... -
Improvement of high strain rate and room temperature superplasticity in Zn-22Al alloy by two-step equal-channel angular pressing
Demirtas M.; Purcek G.; Yanar H.; Zhang Z.J.; Zhang Z.F. (Elsevier Ltd, 2014)The Zn-22Al alloy was subjected to equal-channel angular pressing (ECAP) to improve its high strain rate (HSR) superplasticity at room temperature (RT). A well-designed two-step ECAP process formed an ultrafine-grained ...
