Effect of Plastic Prestrain on the Tensile Strain to Failure of Beryllium.

Abstract

Results of tensile tests on specimens of CIP/HIP P-1 beryllium previously prestressed into the plastic range are presented. Two types of prior deformation are considered, a plastic precompression and a plastic pretension followed by plastic compression. Data from tests involving levels of prestress between 40 and 55 ksi (276 and 379 MPa) show no reduction in the uniaxial tensile strain to failure as a result of prior plastic deformations as high as one percent. An increase in tensile flow stress is observed for the precompressed specimens. (Author)
