Abstract

Bu çalışmada, AISI 410S ferritik paslanmaz çelik saclar farklı kaynak parametreleri kullanılarak plazma ark kaynak yöntemi ile birleştirilmiştir. Plazma ark kaynaklı birleştirmelere kaynak sonrası ısıl işlem uygulanmıştır. Isıl işlemli ve ısıl işlemsiz birleştirmelerin mekanik özellikleri ve mikroyapı incelemeleri karakterize edilmiştir. Çalışma sonucunda, artan ısı girdisine bağlı olarak tane yapısının irileşmesi nedeniyle kaynaklı birleştirmelerin çekme dayanımında ve sertliğinde azalma meydana geldiği tespit edilmiştir. Kaynak sonrası uygulanan ısıl işlemin etkisiyle de tane yapısı irileşmeye devam etmiştir. Kaynak sonrası ısıl işlem uygulanan kaynaklı birleştirmelerin sertlik ve çekme dayanımı ısıl işlemsiz birleştirmelere göre daha düşük bulunurken sünekliğin arttığı belirlenmiştir.

Influence of Heat Treatment on Microstructure and Mechanical Properties of Plasma Arc Welded AISI 410S Ferritic Stainless Steel

Abstract

In this study, AISI 410S ferritic stainless steel sheets were joined with plasma arc welding method by using different welding parameters. Heat treatment was applied to plasma welded joints. This study investigated mechanical properties and microstructure of heat treated and non heat treated plasma welded joints. The study revealed that, there have been decreases in tensile strength and hardness of welded joints because of grain coarsening caused by increasing heat input. Hardness and tensile strength of heat treated welded joints were lower and ductility was increasing compared to the ones of non heat treated welded joints.
