![]() ![]() The discussions are then consolidated through the classification of shrinkage porosity in terms of formation mechanisms and morphology, and its causes relating to composition, design and process conditions. This leads to the well-established interdendritic flow model and commonly-used thermal criteria for shrinkage porosity prediction. A more detailed discussion of interdendritic feeding and mechanisms for shrinkage micro-porosity is then provided. This is followed by characterisation of the solidification phase of steel alloys, including the evolution of phases, which is important in distinguishing between microstructure and porosity in microscopy analysis. It begins with the mechanisms for porosity formation within the solidification contraction phase of the casting cycle, highlighting the importance of feeder design. Authorħ7.040.In this Chapter, shrinkage porosity defects in steel castings are analysed, particularly for low carbon, high alloyed steels, which have applications in critical engineering components.

The illustrations consist of the following: RRE044601 - (Volume I): Medium Voltage (Nominal 250 kVp) X-Ray Reference Radiographs - Set of 34 illustrations (5 by 7 in.) in a 15 by 17 in. These reference radiographs illustrate various types and degrees of discontinuities occurring in steel castings that have section thicknesses up to 2 in. Please Note: This price is for the complete set. Reference Radiographs are nondestructive testing standards universally accepted because of their high reliability in accept-reject actions. ![]()
