Nanoindentation is a common technique for measuring the Young’s modulus and hardness of metals. With recent advancements, nanoindentation can now be used to measure the entire stress-strain curve, even within a single metal grain. Join Sr. Application Scientist Jennifer Hay for a discussion of the theory behind this new measurement, and how nanoindentation measurements of force, displacement, ...

3D printing is the disruptive manufacturing method of the 21st century. In many ways, it is inferior to traditional methods of casting and machining, because microstructure and defects are not well understood or controlled. Yet, the technique is irresistible due to its speed, simplicity, and portability. High-speed nanoindentation is a critical tool for understanding the link between microstruc...

The first and most enduring application of nanoindentation is the characterization of hard coatings designed for mechanical and chemical protection of an underlying material. This session is a live demonstration of standardized nanoindentation with the KLA iMicro nanoindenter to characterize an industrial nitride coating on a tungsten- carbide substrate. Ms. Hay demonstrates sample mounting, in...
