Finite Element Simulation of Canned Forging on TiAl Alloy Containing High Nb

摘要

A rigid plastic finite element simulation method on canned forging was introduced to explain and optimize the large ingot deformation of TiAl alloy containing high content of Nb. By this method the process of deformation and the distribution of stress and strain especially on the interface can be obtained, thus the influence of capsule on the deformation and final shape of ingot can be easily explained and an appropriate processing of canned forging was ingot.
