Effect of commercial purity levels on the mechanical properties of ultrafine-grained titanium
Purcek, G.; Yapıcı, Güney Güven; Karaman, I.; Maier, H. J. (Elsevier, 2011-03-15)Two grades of commercial purity (CP) titanium (grades 2 and 4) were processed using equal-channel angular extrusion (ECAE) at 300 ◦C and 450 ◦C, respectively. The processing temperatures were the minimum temperatures at ... -
Improvement of the fatigue performance of an ultrafine-grained Nb–Zr alloy by nano-sized precipitates formed by internal oxidation
Niendorf, T.; Maier, H. J.; Canadinc, D.; Yapıcı, Güney Güven; Karaman, I. (Elsevier, 2008-04)The formation of nano-sized precipitates in an ultrafine-grained Nb–Zr alloy was investigated. ZrO2 precipitates induced by internal oxidation during heat treatment at low homologous temperatures significantly intensify ... -
Mechanical and wear properties of ultrafine-grained pure Ti produced by multi-pass equal-channel angular extrusion
Purcek, G.; Saray, O.; Kul, O.; Yapıcı, Güney Güven; Haouaoui, M.; Maier, H. J. (Elsevier, 2009-08-20)In this study, pure grade 2 Ti was processed via equal-channel angular extrusion (ECAE) for 8 and 12 passes following route-E at 300 °C. After processing, the microstructural evolution, tensile properties and wear behavior ...
