Title
Elevated Temperature Dynamic Elastic Moduli Of Various Metallic Materials
Description
The dynamic elastic moduli of 40 metals and alloys of engineering interest have been determined at room and elevated temperatures. Modulus determinations were based upon a relation between the speed of sound in a material and its elastic modulus. A specimen of the material was excited electrostatically and its resonant frequency determined. Knowing the geometry of the specimen, the dynamic elastic modulus was calculated.

Room temperature comparisons of dynamic with static moduli were made in most instances using material from the same bar.

The results of dynamic elastic modulus determinations are graphically presented.
