The paper addresses the challenging scientific and technological tasks of achieving limitation of over thickness to 1% of a linear dimension in HIPing Near Net shape PM Components of large size up to 3 meter diameter. To reach this goal it is necessary to increase precision of modeling which has to include thermal conductivity for large (thick) parts, especially influential at the initial...

The non-uniform shrinkage of the tool/canister under hot isostatic pressing (HIP) condition is influenced by many factors, among which the powder relative density distribution seems to have a strong effect. Prediction of the final tool deformation is fundamental for canister design in order to meet dimensional tolerances of final component. To this end, numerical approaches represent a...

In Hot Isostatic Pressing (HIP) of metal powder, anisotropic shrinkage of the capsule induced by inhomogeneity of the initial powder filling density determines the reproducible realization of small geometrical allowances. This becomes a detrimental factor in the manufacturing of near-net-shape components due to their high requirements of the final shape accuracy. This challenge can be solved...
