Using gained experimental data to develop the models of stable flow stresses at high temperature plastic deformation by statistical methods for alloy materials, precision of the models is poor and at the same time the processes of modeling are complicated with great workload.

Effects of pre-treatment,thermomechanical parameters and deformation with steply changing velocity on high temperature deformation behavior of dense FGH95 alloy have been compre- hensively investigated by using isothermal constant strain rate compression test.
