“…This feature of the model makes it difficult to predict the shape change, especially when the stresses contain a deviatory component as shown in Kuhn and McMeeking (1992). Furthermore results from Jeon and Kim (1999) show that micromechanical analysis based microscopic approaches usually amounts to numerical problems and less accuracy. On the other hand, the macroscopic approach can predict the shape changes and is convenient to use for complex geometrical components presented by Abouaf and Chenot (1986), as it has less formulation and fewer parameters compared to the microscopic approach as mentioned in the works of Svoboda and Häggblad (1996) and Cassenti and Dennis (1980).…”

“…Kim et al have simulated the deformation of alumina powder during HIP process [14]. A new FEA model for HIP has been implemented as reported by Jeon et al [15]. Kim has incorporated various diffusion models with the power-law creep model to simulate the densification behavior of 316-L stainless steel during HIP process [16].…”

Hot isostatic pressing of metal powders involves a complex thermal and mechanical coupling process. A constitutive model based on Perzyna's elastic-viscoplasticity equation was proposed, and a Lagrangian finite element method was applied to analyze the large deformation, nonlinear friction, powder flow, and densification behavior during hot isostatic pressing. The mechanical behavior of the powders was analyzed in terms of stress distribution. For comparison to the simulation results, the density, shape deformation, and residual stress of the specimens were evaluated using Archimedes' principle, 3D measuring technology, and Empyrean X-ray diffractometer.

“…Near net shape (NNS) manufacture is an emerging route for producing structural components used in the nuclear industry. Of these, hot isostatic pressing (HIP), the consolidation of an alloy powder in a mould under high temperature and pressure, has been shown to be effective for producing complex geometry components without the need for welds; thus reducing costs, accelerating manufacturing time, and improving performance [1][2][3][4].…”

Stainless steel manufactured by hot isostatic pressing (HIP) has been shown to exhibit significant differences in ductile fracture behavior when compared to equivalently graded forged steel, due to differences in oxide particle concentration between the two manufacture routes. Herein we analyse and quantify the ductile damage characteristics in the fracture process zone of equivalently graded forged and HIP 304L steel using 3D X-ray computed tomography (CT). Ductile void characteristics have been found to vary in size, shape, and spatial distribution; data which are in agreement with the differences in distribution of initiation particles in HIP and forged steel. Using advanced X-ray CT to characterize ductile damage, experimentally determined data can be employed to calibrate existing well-known ductile failure models, developing both our current understanding of ductile failure as well as a predictive tool to simulate fracture in novel HIP components.
