Abstract
A calculation method was used for investigation of the kinetics of stress-strain state in welding of nickel alloy single crystal taking into account anisotropy of its thermophysical and mechanical properties. It is shown that anisotropy of the properties of single crystal promotes for growth of a rate of plastic deformations in temperature interval BTI-II in comparison with isotropic alloy of such type (having polycrystalline structure). The rate of growth of longitudinal plastic deformations in the single crystal in BTI-II temperature interval can approximately 2.0–2.5 times exceed that in the polycrystalline variant of alloy. This should be taken into account in development of corresponding structures and technology of their manufacture. 9 Ref., 3 Tables, 7 Figures.
