Abstract

The mechanical behavior of cubic 𝛾 -nanoparticles is investigated in uniaxial compression. These nanoparticles are freestanding, single crystalline and have a well-defined crystallography related to the cubic geometry (cube faces correspond to the crystallographic { 1 0 0 } -planes). The true values of stress and strain were measured and evaluated. With a true strength of about 3000 MPa to 5000 MPa the nanoobjects reach a significant portion of the theoretical strength. Even after a true strain of about one, no signs of particle damage are observed.
