    Abstract

    A comprehensive characterizing of fine structures in Type 422 stainless steel has effectively related structural parameters to smooth- and notch-tensile properties and to corrosion and stress-corrosion resistance. By a departure from conventional heat treatment for this steel, fracture toughness can be increased nearly fourfold at the same yield strength, and corrosion properties can be substantially improved. These marked improvements in properties are explained in terms of dislocation rearrangements and precipitation strengthening effects.
