Outline of Final Research Achievements

Austenitic stainless steels and nickel alloys have high corrosion resistance and high temperature strength, but intergranular degradations are their conventional and momentous problems. Grain boundary engineering (GBE) can suppress these intergranular degradations by introducing high frequency of coincidence site lattice boundaries into the materials. The authors developed a single-step thermomechanical process for GBE and produced highly intergranular degradation resistant materials by the GBE processing. The grain boundary engineered materials (GBEMs) demonstrated more excellent properties, higher reliability, and longer life than the unGBEed ones. The superiority of GBEMs was confirmed even during manufacturing by examining stabilities of optimized GBEed microstructures and GBE effects by post-GBE straining and sensitization. This study has established the mechanism of GBE effects and the optimization of grain boundary character distribution.
