Webalways the greatest portion of the inclusion. Future research on PM superalloys will concentrate on accurately defining the 3D morphology of inclusions and establishing the quantitative relationship between thermal process parameters and the change in inclusion size. Although many experimental researches on the deformation behavior of non- Webof stringer type inclusions (e.g. TiCN), segregate, shrinkage and porosity. Fluorescent penetrate dye techniques simplify inspection and enable detection of all but the tightest planar flaws. In a production environment the minimum defect length which may be readily detected is approximately 0.4mm but this
