Instantaneous specimen diameter measurements during tensile deformation can be obtained at -452F. Strain at maximum load for the commercially pure and iodide titanium increases with decreasing temperatures. Strain at maximum load for the 300 series stainless steels generally decreases with decreasing temperature to -319F but increases sharply at -452F. The true stress-strain curves obtained at -452F on the 300 series stainless steels do not represent the strain hardening properties of one particular region of the bar as at higher temperatures, but represents the upper envelope of flow stress for various austenite-martensite structure.
