Abstract The extent of the plastically deformed region associated with indentation in silicon carbide is determined by means of selected-area electron channelling. It is found that the extent of the plastic zone beneath an indent is quite large, i.e. equal to about five times the impression radius. Microcrack formation is studied in the SEM, and the combined results are discussed in terms of current elastic-plastic indentation fracture models. The first cracks to form are radial microcracks; their morphology, and the observed indentation plastic zone dimensions, support the elastic-plastic model of Perrott for indentation cracking inα-SiC.
