Abstract

The characteristics of bulk-forming of refractory metal were analyzed, and the effects of strain paths and microstructures on the Mo bulk-forming were discussed. By means of finite element method, metallographic and Electron Backscattered Diffraction (EBSD), the flow and strain distribution of the Mo bulk after multi-direction forging were analyzed. It was found that the metal flow in the core of bulk was intense, and the strain storage energy was the largest. The grain sizes in the core were also larger than those around edges, and there were still some deformed textures in the material. The metallographic results were similar to the Finite Element Method (FEM) results.
