There have been, over the past four decades, various processing schemes introduced that are focused on near net-shape manufacturing of components. These are often based on powder metallurgy approaches, and include hot isostatic pressing (HIP) and additive manufacturing (AM), but more recently include processes such as solid state joining. The full exploitation of these processing schemes has been frustrated by a number of limiting factors including anisotropic and coarse microstructures, issues with prior-particle boundaries, porosity, residual stress, and deficits in certain mechanical properties. This presentation describes an effort aimed at overcoming some of these problems through application of a combination of sophisticated materials characterization and integrated computational materials engineering. The focus has been on the production of equiaxed microstructures and improved fatigue properties of Ti alloys, and the reduction of the influence of ppb’s in Ni-base superalloys. The results of these experiments will be discussed in terms of the increased use of these processing approaches for the manufacture of turbo-machinery.
