[175, 176] Recently, a heterogeneous microstructure design has become an effective strategy to improve the strength-ductility balance. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen. Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. Influence of resistance spot welding process parameters on dissimilar austenitic and duplex stainless steel welded joints.
