Local experimental investigations of the thermomechanical behavior of a coarse-grained aluminum multicrystal using combined DIC and IRT methods

This paper presents investigate the therm BackScattered Diffract with centimetric grai placement and strain fields stitutive modelling of crystal Image Correlation (DIC) and Infrared Thermography (IRT) methods to anical behavior of an aluminum at the microstructural scale. Electron SD) is used to characterize the microstructure of a 3 mm thick specimen ion (EB n size. This study combines the following imaging techniques: DIC to obtain disduring the test, and IRT to estimate temperature and heat source fields f this methodology is to provide energy balance re, in order to propose thermomechanical coninduced by the mechanical loading. Ultimately, the aim o during mechanical test at the scale of the microstructu line plasticity.
