Indentation University Session 1: The Genius of Oliver and Pharr

In Session 1 of the KLA Instruments Indentation University, we introduce the history of nanoindentation technology, starting with the 1992 publication, “An Improved Technique for Determining Hardness and Elastic Modulus using Load and Displacement Sensing Indentation Experiments,” one of the most cited publications in materials science to date. This paper utilized a revolutionary approach to nanoindentation testing.

About this webinar

Session 1 discusses the background and theory of nanoindentation, including the history of development in the field of nanoindentation by Dr. Warren Oliver of KLA Instruments, Professor Sir John Pethica, and Dr. George Pharr. Critical nanoindentation parameters are defined and discussed, and advantages of Oliver and Pharr’s unique approach to nanoindentation testing. This webinar also includes a case study on HY-80 steel, looking at results from elastic modulus and hardness testing.
