A novel in-situ gas-phase alloying approach in wire arc additive manufacturing for controlling solidification mode and designing hybrid stainless steels Chiniforoush, Elina Akbarzadeh; Jandaghi, Mohammad Reza; Moverare, Johan; Saeid, Tohid; Yurtışık, Koray (2025-11-01) This study presents a thermodynamically guided in-situ gas-phase alloying approach in wire arc additive manufacturing (WAAM) to enhance duplex stainless steels by shifting the primary solidification mode from δ-ferrite to ...
Effect of torch path modification on microstructure and mechanical properties in wire arc additive manufacturing of 316L austenitic stainless steel Akbarzadeh Chiniforoush, Elina; Jandaghi, Mohammad Reza; Moverare, Johan; Yazdani, Sasan; Yurtışık, Koray; Warsi, Reyazul (2025-01-01) Mechanical anisotropy is a key challenge in wire arc additive manufacturing (WAAM), which is caused by inherent heat transfer conditions and competitive grain growth during solidification. These factors lead to elongated c...
Influence of Shielding Gas on the Microstructure and Mechanical Properties of Duplex Stainless Steel in Wire Arc Additive Manufacturing Akbarzadeh, Elina; Yurtışık, Koray; Hakan Gür, C.; Saeid, Tohid; Tavangar, Reza (2024-01-01) This study investigates the influence of the shielding gas composition on the microstructural and mechanical properties of wire arc additive manufactured duplex stainless steel. The choice of shielding gas influences the q...
SYNERGIC ARC ADDITIVE MANUFACTURING OF GRADED FERRITIC-AUSTENITIC TRANSITION INTERFACE MATERIALS FOR WELDING DISSIMILAR STEELS Balak, Onur; Çakmak Alpaslan, Hafize; Yurtışık, Koray (2022-10-19)
Effect of Secondary Austenite on Fracture Toughness Properties of Wire Arc Additively Manufactured Duplex Stainless Steels Yurtışık, Koray; Ersan, Batuhan; Akbarzadeh Chiniforoush, Elina; Gür, Cemil Hakan (2022-10-19)
Kara ve su-altı boru hattı sistemlerinde yarı-statik kırılma tokluğu ve kırılma direnç eğrilerinin belirlenmesi Erol, Eren; Tosun, Uygar; Yurtışık, Koray; Gür, Cemil Hakan (null; 2019-11-15) Gaz ve petrol rezervleri genellikle tüketicilerden uzakta bulunur. Yüksek Dayançlı Düşük Alaşımlı (YDDA) çelik plakalardan imal edilmiş ince duvar kalınlıklı boru hatları, rezervlerin taşınma masraflarını düşürmede ekonomi...
Fatigue Cracking of Hybrid Plasma Gas Metal Arc Welded 2205 Duplex Stainless Steel Yurtışık, Koray; Tirkeş, Süha (2014-01-01) Contrary to other keyhole welding applications on duplex stainless steels, a proper cooling time and a dilution were achieved during hybrid plasma gas metal arc welding that provided sufficient reconstructive transformatio...
Characterization of Duplex Stainless Steel Weld Metals Obtained by Hybrid Plasma-Gas Metal Arc Welding Yurtışık, Koray; Tirkeş, Süha; Gür, Cemil Hakan; Gürbüz, Rıza (FapUNIFESP (SciELO), 2013-07-01) Despite its high efficiency, autogenous keyhole welding is not well-accepted for duplex stainless steels because it causes excessive ferrite in as-welded duplex microstructure, which leads to a degradation in toughness and...
