Abstract:

The metallurgical and mechanical properties of several face centered cubic materials 1100 Al, 7075-0 Al, 7075-T6 Al, OFHC Cu and a body centered cubic material Armco iron were examined. Prior to undergoing tensile testing the materials were insured to have a nonoriented equiaxed grain structure and underween chemical analysis and hardness tests. The materials were then tensile tested at 296K in the atmosphere, at 77K in a liquid nitrogen bath, and at 4K in liquid helium. A continuous record of the axial load and of two perpendicular specimen profile traces produced a measurement of specimen true stress-true strain. Engineering stress-strain, elongation, and reduction in area were also calculated.
