Post heat treatment optimization of cold spray additive manufactured Inconel 718 Karakas, Aptullah; Ataee, Arash; Rathi, Amit; Fenercioglu, Tevfik Ozan; Erdoğan, Can; Yalçınkaya, Tuncay (2025-12-01) The cold spray technique has recently emerged as an additive manufacturing method for producing free-standing parts, in addition to its use in repair and coating applications. Manufacturing relatively hard alloys such as I...
Modeling of the Stress Path-Dependent Strain Ratcheting Behaviour of 304L Stainless Steel Through Crystal Plasticity Frameworks Açar, Sadık Sefa; Yalçınkaya, Tuncay (2025-01-01) This study investigates the strain ratcheting behavior of 304L stainless steel under complex stress-controlled cyclic loading conditions employing crystal plasticity models in the DAMASK framework. Strain ratcheting, a phe...
Comparison of Linear and Nonlinear Twist Extrusion Processes with Crystal Plasticity Finite Element Analysis Şimşek, Ülke; Davut, Kemal; Miyamoto, Hiroyuki; Yalçınkaya, Tuncay (2024-03-01) The mechanical characteristics of polycrystalline metallic materials are influenced significantly by various microstructural parameters, one of which is the grain size. Specifically, the strength and the toughness of polyc...
Phase field modeling of fatigue crack growth retardation under single cycle overloads Waseem, Sarim; Erdoğan, Can; Yalçınkaya, Tuncay (2024-02-01) A zone-based crack retardation model that responds to single cycle overloads is applied to a phase field fatigue framework. Fatigue crack growth is incorporated through the degradation of fracture toughness in the phase fi...
Nanoscratching of polycrystalline copper examined through strain gradient crystal plasticity Günay, Enes; Ozdemir, Merthan; Yalçınkaya, Tuncay (2024-01-01) Nanoscratch testing is a method pivotal for evaluating the mechanical and tribological characteristics of materials which involves the controlled scratching of specimens with a nano-scale indenter. This research delves int...
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...
Strain Gradient Plasticity Analysis of Amorphous Plasticity Ünsal, İzzet Erkin; Yalçınkaya, Tuncay (2024-01-01) Amorphous materials lack a defined crystalline structure, exhibiting a disordered atomic arrangement that imparts superb mechanical properties and great potential for applications in many areas. Because of their disordered...
Phase Field Fracture Modelling of Crack Initiation and Propagation in Dual-Phase Microstructures Tatlı, Berkehan; Erdoğan, Can; Ozcan, Mehmed Emin; Yalçınkaya, Tuncay (2024-01-01) Dual-phase (DP) steel's spread in the industry has been fueled by its highly desirable qualities, which include a unique balance of strength and ductility, making it a valuable material for applications ranging from automo...
