So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

Abstract:

Bu çalışmada; savunma sanayi, otomotiv sanayi, petrol iletim hatları gibi sektörlerde yaygın olarak kullanılan ince taneli ve mikro alaşımlı yapıya sahip QSTE 420TM kalitesindeki çelik sac plaka malzeme, Tungsten Inert Gaz Kaynağı yönteminde 1,6 mm ve 2,0 mm çapında ilave metal tel kullanılarak ayrı ayrı birleştirilmiştir. Farklı çaplardaki dolgu tellerine farklı ısı girdileri uygulanmıştır. Böylece kaynak bölgesi (ana malzeme, ısının tesiri altındaki bölge ve kaynak metali)  üzerinde meydana gelen mekanik ve metalürjik değişiklikler, çekme, eğme, çentik - darbe, sertlik testleri ve makrografik, mikrografik muayeneler yapılarak incelenmiştir. Gerçekleştirilen testler sonucunda; 1,6 mm ilave telin, kaynaklı birleştirmenin kendinden beklenen mekanik ve metalürjik özellikleri sağladığı gözlenmiştir. % 44 daha yüksek ısı girdisinin uygulandığı 2,0 mm ilave tel ile yapılan kaynaklı birleştirmelere ait çekme testlerinde ise kaynak metalinden kopma gerçekleşmiştir. Bu sonuçlarla QSTE420TM gibi malzemelerde yüksek ısı girdisinin mekanik ve metalurjik özelliklere olan olumsuz etkileri de incelenmiştir.

Determination Of The Effect Of Additional Metal Wire Diameter On Metallurgical and Mechanical Properties In Tig Welding Of Qste 420tm Steel

Abstract:

In this study; QSTE 420TM quality steel sheet plate material, which is widely used in sectors such as defense industry, automotive industry, oil transmission lines, has fine-grained and micro-alloy structure are combined separately. Different heat inputs are applied to the filler wires of different diameters. Thus, mechanical and metallurgical changes occurring on the welded area (base material, heat affected zone and weld metal) were examined by tensile, bending, notch - impact, hardness tests and macrographic and micrographic examinations. As a result of the tests performed; It has been observed that the 1.6 mm additional wire provides the mechanical and metallurgical properties expected of the welded joint. In the tensile tests of welded joints made with 2.0 mm additional wire with 44% higher heat input, breakage from weld metal was realized. With these results, negative effects of high heat input on mechanical and metallurgical properties of materials such as QSTE420TM were also investigated.
