Summary:

Castings by virtue of their manufacturing process route areprone to induce various defects which are likely to affectadversely during its service life, causing pre-mature failures.Multiple destructive and non-destructive evaluation techniques arepracticed to analyze these defects and suitable measures are takento ensure quality castings and avoid pre-mature failures. Accuratedetection for each type of defect is key factor during analysis toadopt desired modifications in process and /or product stage. Thequality of sound castings is sensitive to multiple factors startingfrom raw material chemical composition to mold design, pouringtemperature conditions and so on. Scanning electron microscopyalong with EDS (Energy Dispersive Spectroscopy) presents promisingtool to analyze these defects with various parameters id est defectsizes, shapes and morphology, elemental composition at defectarea and examination of defect appearance by SE (Secondary) and BSE(Backscattered) electron modes under high and low vacuum to clearlydistinguish each feature of defect. Apart from these advantages,technique liberty of examining defects at very high magnificationsto analyze smallest features and conduct elemental compositionalanalysis to identify the type of defect. This paper describesanalysis of few casting defects observed in grey cast iron by EDStechnique. Emphasis is given to showcase prominent benefits ofusing this technique to ensure correct identification of defect toadopt proper remedial action during casting process.
