Deep cryogenic treatment (DCT) has arisen as a promising green technology to modify the properties of metallic materials. This DCT modified Al-Mg-Si alloy is characterized by nano-scale rod-shaped β’’ precipitates. The LEAP 4000 rarely captures precipitates in their entirety, whereas the ultra-wide-Field-of-View Invizo 6000 captures a number of whole precipitates. This improves our statistical
confidence in the chemistry and geometry of the precipitates and how they affect the alloy’s mechanical properties.
