STRUCTURAL SHEET MATERIALS FOR MISSILE APPLICATION: TENSILE PROPERTIES AT ELEVATED TEMPERATURES,
Abstract
The purpose of this investigation was to determine the effect of elevated temperatures on the tensile properties of several missile structural sheet metals. Two groups of alloys were investigated. These were four types of precipitation-hardening stainless steels: 17-7 PH, PH 15-7 Mo, AM-350, and AM-355; and three types of magnesium-thorium alloys: HM 21XA-T8, HK 31A-H24, and HK 31A-T6. All tensile specimens were tested at room temperature and after a 5-min. soak at elevated temperatures. A stain rate of 0.005 + in./in./min. was used. Test specimens, equipment, and procedures are described in detail. With the exception of the results of AM-355 between 400 and 800 F, the tensile properties of each alloy decreased with the increase of temperatures. Test results are presented in the form of tables and curves to show the effect of elevated temperatures on the tensile properties of the materials under investigation. (Author)
