Cyclic deformation response of ultra-fine grained titanium at elevated temperatures
Sajadifar, Seyed Vahid; Yapıcı, Güney Güven; Demler, E.; Krooss, P.; Wegener, T.; Maier, H. J.; Niendorf, T. (Elsevier, 2019-05)This study focuses on the high-temperature cyclic deformation response (CDR) of ultra-fine grained (UFG) titanium of commercial purity (grade 4) processed via equal channel angular extrusion as a severe plastic deformation ... -
Effect of grain size on the very high cycle fatigue behavior and notch sensitivity of titanium
Sajadifar, Seyed Vahid; Wegener, T.; Yapıcı, Güney Güven; Niendorf, T. (Elsevier, 2019-12)The very high-cycle fatigue performances of coarse-grained and ultrafine-grained titanium samples with different geometries at ambient temperature and various stress amplitudes were investigated. Severe plastic deformation ... -
Severe plastic deformation as a processing tool for strengthening of additive manufactured alloys
Ghobadlou, Ali Hosseinzadeh; Radi, Amin; Richter, J.; Wegener, T.; Sajadifar, S. V.; Niendorf, T.; Yapıcı, Güney Güven (Elsevier, 2021-08)For the first time, the novel combination of multi-pass equal channel angular extrusion/pressing (ECAE/P) and selective laser melting (SLM) was investigated. Herein, four passes of ECAP via route Bc at 150 °C were applied ...
