Strain Rate Sensitivity of Flow Stress at Very High Rates of Strain
1996In order to clarify the mechanism of the steep rise in the flow stress, widely seen in metallic materials at strain rates above about 5×103/sec, two strain rate change tests were conducted. The strain rate reduction test was made for polycrystalline aluminium, copper, iron and niobium at strain rates up to about 2×104/sec.

Strain Rate and Strain Rate History Effects in Two Mild Steels.
1979Abstract : Results are presented of a series of experiments performed with two steels to investigate the dependence of flow stress on strain rate and its history. For this purpose quasi-static, dynamic and incremental strain rate tests were conducted on SAE 1020 hot-rolled steel and SAE 1018 cold-rolled steel at room temperature. It is shown that while

Strain Rate History Effects and Dislocation Substructure at High Strain Rates
1983A brief review is presented of strain rate history and temperature history effects during the high strain rate deformation of metals with special emphasis on the BCC metals. Possible explanations to account for history effects are reviewed. Experiments are described in which single crystals of aluminum are deformed at various strain rates. Observations
