GLUS: Real-time microstructure evolution measurement in-situ

About

LUS is a non-contact method and is thus the technique capable of operating in steelwork environment/on hot samples. The thermo-mechanical annealing simulator (GLEEBLE 3800) gives the possibility for very rapid heating/quenching and/or deformation (tension/compression) of the sample.

With GLUS® it is possible to perform in-situ characterization of the microstructure, for example grain size/growth, texture, austenite condition, transformation characteristic) during simulated hot-rolling. Mechanical properties such as E-modulus and Poisson’s Ratio can also be investigated at different temperatures.
