摘要： A single crystal nickel base superalloy consists essentially of, in weight %, about 6.4% to about 6.8% Cr, about 9.3% to about 10.0% Co, above 6.7% to about 8.5% Ta, about 5.45% to about 5.75% Al, about 6.2% to about 6.6% W, about 0.5% to about 0.7% Mo, about 0.8% to about 1.2% Ti, about 2.8% to about 3.2% Re, up to about 0.12% Hf, about 0.01% to about 0.08% by weight C, up to about 0.10% B, and balance Ni and incidental impurities. The superalloy provides improved alloy cleanliness and castability while providing improved high temperature mechanical properties such as stress rupture life.

摘要： A preweld heat treatment for precipitation hardenable IN939 nickel base superalloy having a gamma matrix and gamma prime strengthening phase dispersed in the matrix comprises heating the nickel base superalloy at about 2120 degrees F. for a time to solution gamma prime phase followed by slow cooling to below about 1450 degrees F. at a rate of about 1 degree F./minute or less, and cooling to room temperature. The preweld heat treatment eliminates strain age cracking at base metal weld heat-affected zone upon subsequent heat treatment to develop alloy mechanical properties.
