Determination of the strain value during severe forming on the multi-axis deformation unit MAXStrain II

Abstract

Severe hot forming methods are effective in grain refinement and controlled development of microstructure. One of these methods is the cumulative deformation on the MAXStrain simulation module. The current state of the issue is briefly discussed in the literary analysis. In the presented research, the basic parameters of the simulation module MAXStrain II cooperating with the Gleeble 3800 hot deformation simulator as well as a new methodology for calculating the equivalent strain value during the cyclic multi-pass multi-axis deformation are introduced. The procedure for development of a unique computational model is presented in the individual steps.
