Intergranular corrosion relationships

Relationship of Alloy Microstructure to Susceptibility to Intergranular Corrosion... [Pg.340]

The Fe-Cr-C Equilibrium Relationships in Stainless Steels. The metallurgical processes occurring in austenitic stainless steels causing susceptibility to intergranular corrosion (sensitization) and methods to either prevent or remove susceptibility, are illustrated by the physical metallurgy of the selected alloys in Table 7.5. These are all austenitic stainless steels, and after quenching from elevated temperatures are es-... [Pg.342]

According to electrochemical theoiy, susceptibility to inteigranular corrosion is a prerequisile for susceptibility to see, and treatment of aluminum alloys to improve resistance to See also improves their resistance to inteigranular corrosion. For most alloys, however, optimum levels of resistance to these two types of fiiilure require efifferent treatments, and resistance to intergranular corrosion is not a reliable indication of resistance to SCC. The relationship between intergranular corrosion and SCC is furfoer described in Chapter 4. [Pg.101]
