FIRST PROGRESS REPORT TO MATERIALS LABORATORY WRIGHT AIR DEVELOPMENT CENTER ON EFFECT OF PRIOR CREEP ON MECHANICAL PROPERTIES. Period covered: April 1, 1959 to June 30, 1959

Technical Report ·
OSTI ID:4157529
BS>Progress in a study of ereep damage to short-time mechanical propenties of aircraft structural materials is reported. Activities during the period included selection of test materials and preparation of test equipment. Limited studies were made of Rene 41 and Udimet 500 alloys to aid in material selection. Damage to these materials was pro- duced by a creep exposure at 1700 deg F. Studies were conducted on the 80 Ni--20 Cr alloy to establish the annealing conditions necessary to produce fine grain and coarse grain conditions for creep damage. (J.R.D.)
