Dynamics of phase transformations and microstructure evolution in carbon-manganese steel arc welds using time-resolved synchrotron X-ray diffraction.
Phase transformations that occur in both the heat-affected zone (HAZ) and the fusion zone (FZ) of a carbon-manganese steel spot weld have been investigated using time-resolved X-ray diffraction (TRXRD) with time resolutions down to 50 ms. It is found that in both zones the gamma(f.c.c.) --> alpha(b.c.c.) transformation on cooling is twice as fast as the forward transformation of alpha --> gamma...
متن کاملThe Influence of Heat-Input on Structural and Mechanical Properties of 2205 Duplex Stainless Steel
The influence of heat-input and pre-heat treatment on the structure, mechanical and corrosion behaviors of 2205 duplex stainless steel joint by means of GMAW process was the goal of this study. In this regards, the welding process was done using different heat input in the range of 0.6 to 1.4 kJ/mm and different pre-heating treatments in the range of 25 to 100 oC. The microstructural properties...

متن کاملStudy on Static Recrystallization Process in Duplex Stainless Steel 2205
Steel 2205 is one of the most famous duplex stainless steels. The microstructure of this steel composed of ferrite and austenite in similar amount. Therefore, in order to improve mechanical properties through microstructure, thermo mechanical processes such as controlled hot rolling and forging should be applied. It is not possible to employ the usual heat treatment. It shows the importance of ...
متن کاملInterface and Heat-affected Zone Features of Dissimilar Welds between AISI 310 Austenitic Stainless Steel and Inconel 657
The aim of this paper is to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 for use in oil-refining industries. The welds were produced using four types of filler materials; nickel-based alloys designated as Inconel 82, A, 617, and 310 SS. The interfaces and heat-affected zones were characterized by optical and scanning electron microscopy. Interfaces on the two sides...
