Orientation dependence of creep in Ni3Ge single crystals
The creep of Ni3Ge alloy single crystals oriented along [001], $$[\bar 139]$$, $$[\bar 234]$$ and $$[\bar 122]$$ strain axes is investigated. It is established that the transition from an octahedral to a cubic slip raises the alloy’s resistance to creep deformation. The slip in cube planes demonstrates the high stability of the rate of steady-state creep with respect to changes in the testing temperature.
