Characterisation of a functionally graded duplex stainless steel: fabricated by Gas Tungsten Arc Welding

Functionally graded materials (FGM) are a class of materials in which the chemical composition or microstructure varies as a function of position, offering unique material properties. In this study, a functionally graded structure was manufactured using Gas Tungsten Arc Welding and a double wire feed device. The wire feed rate was changed step...
