Structure and mechanical properties of Ni3Ge single crystals under severe plastic deformation and heating

Resumo

Mechanical tests are performed for Ni₃Ge alloy single crystals in the intense plastic shear deformation scheme under quasi-hydrostatic pressure at different test temperatures. Dependences of resistance to shear deformation on the Bridgman anvils’ angle of rotation are obtained. The microrelief of the surface damage of Ni₃Ge single crystals fractured by plane bending after specimens were withdrawn from the Bridgman anvils is studied. X-ray diffraction patterns of deformed Ni₃Ge single crystals are obtained.
