The foIlowing tensile propenties of Brush Reryllium QMV material, vacuum hot pressed at 1050 deg C, are reported for temperatures ranging from 70 to l600 deg F: yield strength, uitimate strength, modulus of elaaticity. percent elongation, and stress-strain relationship to 5% elongation. A unique method for obtaining strain measurements is described. Only one or two specimens were used for each temaperature and the coupon configurations governed the testing methods. Because of this, the test resuits, while accurate, were based on insufficient samplings to establish representative material properties. With the exception of the modulus of elasticity, which showed variations, the general behavior of the material was similar to that previously reported. A detailed comparison of test results with those ln other published data is impossible because chemical composition, mesh, compacting pressure, machining precedures, and type of surface finishing treatment are not defined for the beryllium materials discussed.
