The purpose of the report is to make available to the design engineer tensile property data on 5052-H34 aluminum under conditions of rapid heating and loading. The tensile property data reported are ultimate tensile stress, ultimate yield stress at 0.2 percent offset, elastic modulus, percent total elongation, and percent uniform elongation. The uniform elongation was determined only at 0.0045 in.in.sec on the transverse specimens. These tensile properties were determined at strain rates of 0.0045, 0.0262, and 0.0419 in.in. sec and at temperatures from room temperature 78F to 700F at 100-degree intervals, excluding 100 and 200F. The time required to reach the test temperature was, in most cases, less than 10 seconds. In addition to the tensile property data, the angle of fracture of the material was also determined. These data are presented as byproducts of the tensile property data and only to investigate the possibility of establishing a trend for the angle of fracture at different strain rates and temperatures. Primary consideration is given to ultimate tensile and yield properties.
