Analysis of hot deformation behavior and forecasting damage in the forging process of Waspaloy alloy

Abstract eng:
In this paper, the analysis of the three-dimensional strain state for the cogging process of forgings made of the Waspaloy alloy with the application of the finite element method was presented. For the numerical simulations, a commercial and professional plastic forming software DEFORM 3D (2018) was applied. The results of work connected with the simulation of the diagram of metal flow and thermal phenomena in the hot forging process in V- shaped anvils, which were complemented by means of the addition of forecasting the damage in the course of forging, were presented. The assessment of the distribution of the effective stress, the mean stress, temperature, and also the damage factor in the volume of the billet being strained was performed. Good agreement between theoretical and experimental results was observed.
