Effect of grain refinement and phase composition on room temperature superplasticity and damping capacity of dual-phase Zn-Al alloys

Demirtas M.; Atli K.C.; Yanar H.; Purcek G. (Cambridge University Press, 2018)

The effects of grain refinement and phase composition on superplasticity and damping capacity of eutectic Zn-5Al and eutectoid Zn-22Al alloys were investigated. For grain refinement, equal-channel angular pressing (ECAP) ...
Effects of grain size on room temperature deformation behavior of Zn–22Al alloy under uniaxial and biaxial loading conditions

Cetin M.E.; Demirtas M.; Sofuoglu H.; Cora Ö.N.; Purcek G. (Elsevier Ltd, 2016)

Effects of grain size on room temperature (RT) deformation behavior of superplastic Zn–22Al alloy under uniaxial and biaxial loading conditions were investigated. Two–step equal channel angular pressing (ECAP) and subsequent ...
Optimization of strength, ductility and electrical conductivity of Cu-Cr-Zr alloy by combining multi-route ECAP and aging

Purcek G.; Yanar H.; Demirtas M.; Alemdag Y.; Shangina D.V.; Dobatkin S.V. (Elsevier Ltd, 2016)

Properties of Cu-Cr-Zr alloy with ultrafine-grained (UFG) structure produced by equal-channel angular pressing (ECAP) via different routes have been investigated. Special attention was paid to the optimization of ...
