In the present investigation, influence of joint design on microstructure and mechanical properties SAF 2205 duplex stainless steel welds are reported. Plates with two different designs were welded using gas tungsten arc welding process. To investigate sole effect design, joints designed in such a way that both have similar groove volumes. The weldments investigated for microstructural characte...

Abstract Duplex stainless steels (DSS) have a microstructure consisting of 50% ferrite α and austenite γ. This two-phase provides the duplex with attractive mechanical corrosion properties. However, is very dependent on heat treatment chemical composition. During welding process, temperature reached in heat-affected zone (HAZ) retransforms into ferrite. Due to high cooling rates, only part retr...

Ikaite, CaC03 . 6 H20, is monoclinic, C2jc, with a = 8.792(2), b = 8.310(2), c = 11.021(2)A, P = 110.53(5)°, Z = 4. With 2205 independent reflectionstaken at 25°C of a naturally grown crystal specimen the structure was refined to a weighted Rw = 0.028. The C03 group is planar with C0 distances 1.279(2) and 1.290( 1) (2 x) A. The hydrogen bond network is determined. The optical behaviour is expl...
