Report presenting an evaluation of buckets of S-816 alloy removed from two J47 engines overtemperatured in service operation. Engine results indicated that the overtemperatured buckets did not fracture in abnormally short operating times. Cracking, particularly on the leading edge, was the principal mode of failure of the buckets.

The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA).
The Technical Report Archive & Image Library (TRAIL) identifies, acquires, catalogs, digitizes and provides unrestricted access to U.S. government agency technical reports. The mission of TRAIL is to ensure preservation, discoverability, and persistent open access to government technical publications regardless of form or format.
