The influence of initial porosity of copper powder billets on values of ultimate degrees of deformation at uniaxial tension, compression and torsion has been investigated theoretically and experimentally. The technique of determination of ultimate degrees of deformation for powder materials using results of compression test by sequential analysis of plastic equilibrium of billet’s points with Lyapunov’s functions method and their microstructures after deformations. The investigation results were implemented during development of production technologies of powder details.Downloads
