A collaboration between ONERA and Michalex

In collaboration with Michalex, we are pleased to offer high temperature instrumented indentation systems (HTIIS). These instruments, developed by ONERA, the French Aerospace lab, are specifically devoted to very high temperature mechanical testing, up to 1000°C : HTIIS 1000 and 1200°C: HTIIS 1200.
This unique combination of mechanical micro probe and temperature control technology allows access to mechanical properties at nano and micro scale at extreme temperatures.

Design:

As any indentation system, the instrument basically measure load and displacement as well as temperature during the entire experiment. An optical microscope allows the user to visualize the indents at temperature immediately after the test.

Unique solutions have been implemented to enable accurate measurement of the indentation behavior at these extreme temperatures. A very precise control of the temperature is required to limit the effects of thermal dilatations. A unique design for both load and displacement measurements and actuators minimizes the impact of thermal drift. In addition, a very high stiffness design enhances the accuracy of the indenter penetration measurement.

A combination of smart choices for temperature probes and control algorithms with mechanical design for the indentation measurement results in unmatched level of performance in a temperature controlled mechanical testing system.

Last but not least, the operating software combines ease of use and flexibility of experiment design. In addition, state of the art standard instrumented indentation data analysis rootines and algorithms allows the user to quickly calculate the mechanical properties and share his data with the scientific community.
