Dwell fatigue fracture in Ti microstructures through crystal plasticity and phase field fracture frameworks Bulut, Orhun; Erdoğan, Can; Yalçınkaya, Tuncay (2024-01-01) Titanium alloys, due to their advantageous properties are used to construct key components in aero-engines. However, their susceptibility to dwell fatigue conditions has been known to lead to a severe reduction in function...
Observation of heterogeneous deformation microstructure in ECAP processing of high-purity niobium Ikeda, Satoshi; Miyamoto, Hiroyuki; Yuasa, Motohito; Yalçınkaya, Tuncay; Bulut, Orhun; Günay, Enes (2023-11-28)
A comparison of predictions from micropolar and strain gradient crystal plasticity theories for textured oligocrystals Tandoğan, İzzet Tarık; Bulut, Orhun; Budnitzki, Michael; Yalçınkaya, Tuncay; Sandfeld, Stefan (2023-05-30) Novel additive manufacturing techniques often result in strongly textured microstructures with anisotropic grain structures. In the example of cold spraying, the grains are flattened in build direction due to severe plasti...
Crystal plasticity modeling of additively manufactured metallic microstructures Acar, Sadik Sefa; Bulut, Orhun; Yalçınkaya, Tuncay (2021-01-01) Different manufacturing processes such as flow forming, rolling, wire drawing and additive manufacturing induce anisotropic grain structure and texture evolution at the micro scale, which results in macroscopic anisotropic...
The influence of thickness/grain size ratio in microforming through crystal plasticity Bulut, Orhun; Acar, Sadik Sefa; Yalçınkaya, Tuncay (2021-01-01) Microscale forming operations have become popular due to miniaturisation which focuses on micro scale design and manufacturing of devices, components and parts, e.g. in RF-MEMS. In such processes when the component dimensi...
