Effect of friction stir processing on the fatigue performance of AZ31 magnesium alloy
Yapıcı, Güney Güven; Sajadifar, S. V.; Ghobadlou, Ali Hosseinzadeh; Wegener, T.; Sobrero, C.; Engelhardt, A.; Niendorf, T. (Wiley, 2023-05)Herein, the cyclic mechanical behavior of AZ31 magnesium alloy after multipass friction stir processing (FSP) is investigated up to the very high-cycle fatigue (VHCF) regime. The grain refinement and texture evolution after ... -
On the friction stir processing of additive-manufactured 316L stainless steel
Sajadifar, S. V.; Ghobadlou, Ali Hosseınzadeh; Richter, J.; Krochmal, M.; Wegener, T.; Bolender, A.; Heidarzadeh, A.; Niendorf, T.; Yapıcı, Güney Güven (Wiley, 2022-10)The novel combination of friction stir processing (FSP) and additive manufacturing (AM) is studied herein. Laser-based powder bed fusion of metals (PBF-LB/M) is used to establish 316 L stainless steel with a bimodal ... -
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 ...
