| Abstract |
In the work with the purpose of determining the prospects of using the kinetic physical and
mathematical theory of creep of metals for performing design calculations when creating new technology products, the results obtained in describing the theory of uniaxial creep processes of 1570P alloy
under conditions of steady-state and abrupt changes in thermomechanical loading parameters are presented. It is established that the new physical and mathematical theory of creep of metals being developed, which, unlike the classical phenomenological theory, takes into account the structure of the
metal and its change in the creep process, equally well describes the process under steady-state and
non-stationary conditions of thermomechanical loading. The important role of the structural state of the metal on the creep process is shown. The main structural parameter determining the characteristics of the process is the scalar density of immobile dislocations. |
