This course describes how the shape of casting features influence the Neutral Thermal Axis (NTA) and hence the location and distribution of porosity. It describes shapes that facilitate placing the porosity where it will not be detrimental to the function of the casting. It shows how the designer can identify the proper location and distribution of the porosity and how to specify the NTA and local porosity requirements so the die designer and process control technician will understand what the casting needs.
