Physicomechanical properties of volume-strained sintered porous nickel

Measurement of the velocity of propagation of longitudinal USV in sintered solids offers a highly sensitive means of detecting contact imperfections and artificial defects and also of examining their healing during sintering.
An evaluation of macrodefect concentrations based on ultrasound-velocity measurements established that cold healing of defects is possible at high repressing pressures.
Ultrasound velocity measurements revealed an appreciable anisotropy of macrodefects forming during sintering and re-pressing in porous nickel sintered with a volatile pore-forming agent.
