This article provides a brief introduction to a dynamic micro-indention measurement technique which can be useful to characterize materials that are hard to analyze using the well-known Vickers and Knoop measurements described in ASTM E364.

Ultrasonic fatigue testing is importance for materials intended for high endurance, high reliability applications.

This article describes a novel micro-compression instrument and technique for determining the hardness of individual particles using controlled uniaxial compression. Brief examples of the technique used to characterize and compare the hardness of battery anode materials are provided.
