Superalloys 2004 (Tenth International Symposium)
A statistically based approach was completed to assess the effect of microstructural (and associated heat treatment processing parameters) on the 649 o C capability of two advanced powder metallurgy (P/M) superalloys. The results showed that microstructure and processing play a key role in achieving a balance of mechanical properties. For a desired combination of good high temperature capability the results indicate that a supersolvus heat treatment followed by a fast cooling rate is desired.doi:10.7449/2004/superalloys_2004_341_350 fatcat:6rcrpuc325fitnavkzutrjw4me
