Effect of Process Parameters on Microstructure and Mechanical Properties of Duplex Stainless Steel Produced by Wire-Arc Additive Manufacturing, M.Sc. Thesis Sharif University of Technology ; Ashouri, Hossein (Supervisor) ; Movahedi, Mojtaba (Supervisor)
Abstract
Wire-arc additive manufacturing is one of the types of additive manufacturing methods that creates the desired part through layer-by-layer deposition. Heat input and interlayer temperature have an important role in this process. Duplex stainless steels have a wide range of applications due to their high corrosion resistance in chloride environments and higher strength than austenitic stainless steels. In this study, the effect of heat input (0.3 kJ/mm and 0.8 kJ/mm) and interlayer temperature (250 ºC and 40 ºC) was investigated on the macrostructure, microstructure and mechanical properties of 2209 duplex stainless steel walls that produced by gas metal arc welding based wire-arc additive...
