Influence of hydrostatic pressure on the ductility of copper as a function of its initial state
S. A. Egorov Saint Petersburg State University
Abstract:
The influence of hydrostatic pressure in the interval 0–250 MPa on the deformation properties of copper versus its initial state is studied. After liquid nitrogen storage, the torsion strain to fracture is found to increase when the pressure rises to 200 MPa. As the pressure rises further and reaches 250 MPa, the torsion strain to fracture drops. Preliminary torsion to a strain of 5% in opposition to torsion under pressure makes the pressure dependence of the ultimate strain linear. If the prestrain equals 25%, a rise in the pressure to 150MPa increases the ductility of the material. A further increase in the pressure to 250 MPa changes the ductility insignificantly.
