Selection of optimal path of strain rate change in the process of multistage hot deformation under the condition of the equal duration of stages

For solving the problem of rate mode of multistage hot deformation optimization in order to reduce the impact of the stages number on the structure of a nonlinear programming problem, it is suggested to search the solution in the form of multistage rate change with the equal duration of stages and with rate change by the path, set by polynomial and exponential functions.
