Anton Paar has published an Application Report on the efficiency of its High Temperature Ultra Nanoindentation Tester (UNHT3 HTV) for measuring mechanical properties up to 800°C.
There has been some debate about the best way to perform elevated temperature nanoindentation tests, with thermal drift, noisefloor and tip erosion topping the list of issues which can hamper such experiments. Anton Paar TriTec's work has culminated in the release of its High Temperature Ultra Nanoindentation Tester (UNHT3 HTV). Its development has been aimed at solving the issue of thermal drift - one of the main issues that will cause error in elevated temperature tests, with drift rates tending to increase with temperature.
The heart of the UNHT3 HTV is based on the successful and patented Ultra Nanoindentation Tester. Its measurement head is optimised for high temperature operation and combined with a patent-pending sample stage which enables measurements to be performed at any temperature within the operating range with the highest possible thermal stability.
