An experimental investigation of the deformed zone associated with indentation hardness impressions

Abstract Using a metallographic method and specimens of 70 : 30 brass, experimental determinations have been made of the elastic-plastic and other low-strain boundaries of the deformed zone associated with indentation hardness impressions. Pyramidal impressions in specimens of semiinfinite and finite thickness, pyramidal impressions made close to the edge of the specimen, and ball impressions made under a range of indenting conditions have been investigated. The results suggest that indentation by the standard pyramidal indenter occurs in this particular material by a compression type of mechanism rather than by a cutting type of mechanism on which theoretical treatments of the indentation process have been based. The practical significance of the results is also discussed.
