Abstract:

Typical effects of increasing the strain rate to nearly 100 in.in. min at room and elevated temperatures on the tensile properties of a number of commercial alloys are discussed. A bibliography is included of information on specific effects of moderately high strain rates on these AND OTHER ALLOYS. Plots of typical data for a number of commercial alloys illustrate the following general trends resulting from increasing the strain rate at room temperature, the yield and ultimate tensile strengths of a given alloy either are not affected or are increased slightly as the strain rate is increased at slightly elevated temperatures, the effect of increasing the strain rate is generally similar to that at room temperature, if the alloy has negligible tendency to creep at stresses lower than the yield strength and remains in a stable condition and at high temperatures, increasing the strain rate causes substantial increases in the yield and ultimate strengths, if the alloy tends to creep at stresses lower than the yield strength.
