| Research Abstract |
Stainless steels and nickel alloys have high corrosion resistance and high temperature strength, but intergranular degradations are their conventional and momentous problems. The authors have produced highly intergranular degradation resistant materials with commercial austenitic stainless steels and nickel alloys by grain boundary engineering. The grain boundary engineered materials demonstrated much more excellent properties, higher reliability, and longer life than ordinary stainless steels and nickel alloys. This study has developed a thermomechanical processing for grain boundary engineering.
