Abstract : Anodized hot-pressed beryllium has been experimentally evaluated. Tensile, thermal expansion, oxidation-resistance, and stress-corrosion evaluations were performed on material representing one lot of 2-percent BeO (maximum) beryllium hot-pressed bar stock. Tensile evaluations were conducted at room temperature, 1000, 1600, 1800, and 1900 F. Six specimens, representing longitudinal and transverse material orientations, were evaluated at each temperature. The strength of the transverse material was greater than that of the longitudinal material at room temperature. There was no apparent effect of material orientation on the strength properties at the elevated temperatures.
