摘要
A simple easy-to-use model for Hot Isostatic Pressing (HIP) with cylindrical containers is proposed. This model provides a simple description of stresses and strains in both the powder and can during the HIP process. The model is also used to prove that the radial shrinkage of the powder is always greater than the axial shrinkage. Results are compared with finite element calculations; the good agreement between the two sets of computations shows that the simplified proposed model realistically describes the HIP process. Finally the model is used to estimate the effects of rheology of the powder and of the can as well as the effects of geometry on the final non-isotropic deformation of the container.
