“…Because of the tests, an increase of approximately 5.5% and 4.5% was observed (QM and QP), respectively. The deformation amount increased with the effect of temperature effecting the HAZ and the tensile strength increased accordingly [41], [42].…”

In this study, it has been reported that Q345B steel combine with different steels using electric arc welding method and the mechanical properties were investigated. Produced by hot rolling processes, Q345B steel is a low-alloyed medium tensile strength and highly usable steel. The steel used contain less than 0.2% carbon and less than 0.55% silicon, chromium and nickel. In this study, Q345B steel generally used at low-pressure/temperature zones in thermal power plant (boiler wall etc.) is combined with 16Mo3 and P265GH steels. The Q345B steel is welded to make the mechanical properties easy to compare. After joining, specimens were collected from the welded areas and used in the preparation of mechanical and metallographic processes. In this process, all joints were subject to tensile, charpy, hardness and bending tests. In addition, the collection of macro images from welding were used in observation of transition zones which were operated. Electrodes with a basic character cover were used (E7018) as filler metal in the joining processes. All mechanical tests met the requirements of the relevant standards and all welds were identified as valid weld. Bu çalışmada Q345B çeliğinin farklı çeliklerle elektrik ark kaynak yöntemi kullanarak birleştirilmesi ve mekanik özellikleri incelenmiştir. Sıcak haddeleme işlemleri ile üretilmiş olan Q345B çeliği düşük alaşımlı orta gerilmeli mukavemet değerlerine ve oldukça fazla kullanım alanına sahip bir çeliktir. %0.2 den daha az karbon içeren bu çelik %0.55 den daha az oranlarda silisyum, krom ve nikel ihtiva etmektedir. Bu çalışmada, genel olarak termik santrallerde (kazan duvarı gibi) düşük basınç ve düşük sıcaklık alanlarında kullanılan Q345B çeliği; 16Mo3 ve P265GH çelikleri ile birleştirilmiştir. Mekanik özelliklerinin karşılaştırmasının kolaylıkla yapılabilmesi için Q345B çeliği aynı zamanda kendisi ile de kaynak edilmiştir. Yapılan birleştirmeler sonrasında kaynaklı bölgelerden numuneler çıkartılıp mekanik ve metalografik işlemler için hazırlanmıştır. Bütün birleştirmeler sırasıyla çekme, çentik darbe, sertlik ve eğme testlerine tabi tutulmuşlardır. Bunların dışında geçiş bölgelerini gözlemlemek için tüm kaynak dikişlerinden makro görüntüler alınmıştır. Birleştirme işlemlerinde dolgu metali olarak E7018 kalite bazik elektrot kullanılmıştır. Tüm mekanik testler ilgili standartların şartlarını sağlamış ve tüm kaynaklar geçerli bir kaynak olarak tanımlanmıştır.

“…However, when structural behaviours involving partial steel necking or damage are concerned, true stress-strain relation after the onset of necking is necessary for structural FEA. It cannot be conveniently estimated according to the descending stage of engineering stress-strain curve due to strain localization effect [10]. From the damage mechanics perspective, the process from the initial necking to the fracture of a tensile coupon could be regarded as a standard ductile damage process.…”

S275 and S690 structural steels are analysed based on experimental results [10]. Combined linear and power stress-strain laws are used to describe the damaged stress-strain relations after necking and compared with results available [10].…”

A calibration procedure for material damage models of S275 and S690 structural steels is proposed based on their full range engineering stress‐strain curves. Combined linear and power stress‐strain laws with a weighting factor are used to describe damaged stress‐strain relations after necking. Material damage models are proposed based on the estimation of undamaged stress. Tensile coupon tests on S275 and S690 steels are modelled in ABAQUS with the explicit solver. Results show that the numerical engineering stress‐strain curves based on the proposed damage models are very close to the experimental results. An investigation is made to establish the damage susceptibility for S275 and S690 steels.
