Abstract

The determination of mechanical properties of materials at elevated temperature presents difficulties, particularly when the material to be tested is subject to oxidation. Various methods have been employed to permit the evaluation of high temperature creep properties. The method described in this paper was developed on the basis of modifications of a technique developed for the protection of high temperature fatigue specimens. The method involves encasing the creep specimen in a flexible capsule which is capable of withstanding exposure to the atmosphere for extended periods at temperatures up to 1000C.

Extensive testing of materials such as uranium and tantalum has provided the basis for claims relative to the effectiveness of this technique.
