High Temperature Testing
ARAMIS is routinely used for measurements of deformations and strains at temperatures up to 1200 degrees C, and has also been used at higher temperatures, for re-entry protection system evaluations. One common measurement is to determine differences in material properties for alloys at room temperature versus elevated temperature. ARAMIS can also be used to evaluate dynamic strains during welding and cooling, and plastic deformation and strain after final cooldown - which is also an example of long term condition monitoring. Pre-test and post-test images are compared, and the sensor is moved and reconfigured between the measurements.
Pattern application for high temperature measurements is straightforward. Usually aluminum oxide is applied directly to the bare substrate.
