Applied Load, Environment, and Time as External Determinants of Ceramic Hardness

  • I. J. McColm


In Chapter 1 applied load and sample grain size were highlighted as two variables affecting the determination of “absolute” hardness values for ceramic materials; Figures 1.2 and 1.3 emphasize the point. The load variation of hardness is better called the indentation size effect, ISE, because this emphasizes the volume dependence of hardness when this property is determined by a pyramidal indenter.
