PROGRAM TO DEVELOP A WROUGHT BLADE SUPERALLOY

摘要

This report presents the current status of a wrought super-alloy development program involving modifications of an Astroloy base. The goal was an alloy with 100-hour average life at 1900°F and 15s 000 psi. The goal has not been met by the variations employed to date, although various chemistries reported appear stronger than the best nickel-base superalloy currently in production.
