Volume 19, Issue 6 (November 1991)
This book was written with the aim of increasing the awareness of materials scientists, metallurgists, and engineers of recent developments in hardness testing of modern ceramics. Hardness is not a unique property, but is a response of the material to a specific indentor and test conditions. Several models of hardness are presented including simplified elastic or elastic plastic models, which set bounds upon the hardness limits. The sensitivity of hardness to crystallographic influences is well covered. The book covers the common test methods such as Mohs, Rockwell, Vickers, and Knoop, as well as less well known methods such as Berkovich and scratch hardness. Substantial progress has been made in recent years in utilization of microindentation methods to study fracture toughness, residual stress surface layers, and wear processes in ceramics.
