Abstract Scope |
Grain Boundary Engineering (GBE) of Type 304 stainless steel have shown improvement on stress corrosion cracking behavior in boiling saturated magnesium chloride solutions. The microstructure development by applying thermo-mechanical processes revealed increased population of intergranular resistant twin related boundaries. The grain boundaries character distribution and grain boundaries network connectivity were analyzed to elucidate the materials behavior in the corrosive environment. Evidence of intergranular corrosion resistance by fractographic examination showed the role of twin related clusters in improving the time to failure as well as the rate of elongation for the materials tested.
GBE can be an effective process to enhance the performance of stainless steels in corrosive environments however, the thermo-mechanical processes needed for GBE have to be well designed to obtain optimal microstructure. |
