Abstract The effects of hydrostatic pressures in the range 0.1 to 600 MPa on the tensile fracture of a free machining brass have been studied. In agreement with the results of earlier workers, the natural strain to fracture was found to increase rapidly with pressure for pressures up to 300 MPa, but to increase less rapidly at the higher pressures. The rapid increase in ductility under confining pressures up to 300 MPa is shown to be due to the suppression of void development, by the pressure, u...

Abstract Precipitation in chromium-nitrogen alloys containing 0.011 and 0.014% nitrogen has been followed by resistivity and hardness measurements on specimens quenched from 1200°C and aged between 125° and 400°C. Precipitation followed a single-stage, diffusion controlled process, which in the early stages obeyed the equation W = kfn in which the shape-dependent exponent n had a mean value 1.38, approximating to the value 3 2 derived by Zener for spherical-type precipitates. Activation energies...
