- •
Designed a new ODS austenitic alloy composition to suppress the detrimental (delta and sigma) phases
- •
Synthesized the alloy through powder metallurgical process and has the hardness of 340 HV.
- •
Ultra-fine grain structure and even distribution of dispersoids (9 nm) in the alloy the observed to enhance hardness.
