Abstract

Elastic moduli in tension and in shear have been determined at various temperatures between 75 and 1500 F for 21 different commercial steels, both carbon and alloyed.

With increasing temperature both the tensile and shear moduli decrease approximately linearly until a certain temperature is reached beyond which a more rapid decrease is observed; this temperature is 700, 900, and 1300 F for carbon, alloyed ferritic, and austenitic stainless steels, respectively. Poisson's ratio does not change significantly with temperature.

Very good agreement is found between the data obtained in this investigation and results, determined both statically and dynamically, that have been reported by various other investigators.
