Low-carbon steels are the first option when designing with steel. They offer good machinability and excellent weldability. To some extent, the strength and ductility can be manipulated by various thermal and mechanical processes, such as working, annealing, and carburization. This session is a live demonstration of standardized nanoindentation with the KLA iMicro nanoindenter to characterize co...

In its most basic form, instrumented indentation involves pressing an indenter of known geometry into a test surface while continuously monitoring force and displacement. In this session, we review the test and analysis commonly known as the “Oliver-Pharr” method for measuring hardness and Young’s modulus. The continuous measurement of force and displacement affords two important advantages ove...

In 1992, Warren Oliver and George Pharr published an article that revolutionized hardness testing. The genius of Oliver and Pharr was that they devised a way to know the size of a hardness indentation without imaging it. This development disrupted Vickers and Knoop microhardness testing, which required direct measurement of the lengths of the indentation diagonals. Not having to image the inden...
