Compression Experiments on γ′-Nanoparticles

الملخص EN

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 {100}-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.
