in the present study, the microstructural changes of a nickel based superalloy nimonic80a during a non-isothermal deformation were studied. therefore, microstructure evolutionduring hot side pressing test was predicted with combined methods of finite element analysis andprocessing map of the material. the predicted results were validated through experimentalmicrostructural studies. the results ...

Preform design in forging processes is an important aspect for improving the forging quality and decreasing the production cost. The objective of this paper is to obtain an optimal perform shape in the consideration of the influence of the metal flow deformation in closed die forging process. Finite element method based DEFORMTM 3D software in conjunction with Taguchi method has been used to si...
