Description
Liquid metal dealloying is a promising method relying on the selective dissolution of a component from a precursor alloy into a liquid metal, resulting in production of bicontinuous porous surface on the precursor alloy. To expand use of the porous structures fabricated by liquid metal dealloying, welding of the precursor alloy would be needed. In this study friction stir lap welding of 430 stainless steel to Fe-Ni-Cr precursor alloy was done, and then the weld microstructure was examined. Cast and cold rolled Fe₅₆Ni₃₀Cr₄ precursor alloy 1.5 mm in thickness, was placed on 430 ferritic stainless steel, and then friction stir lap welding was conducted using a CS4-shaped Q60 welding tool.
