What is it about?
Exposing materials to hydrogen environments leads to degradation of mechanical properties, hydrogen embrittlement (HE), and failure. While the current approach for assessing hydrogen's impact on materials involves mainly multiscale modeling and mechanical testing, there is a significant deficiency in detecting the intricate interactions between hydrogen and materials at the nanoatomic scales and under in situ conditions.

Why is it important?
This perspective review highlights the experimental endeavors that will bridge this gap, pointing toward the imminent need for new experimental techniques for detection and mapping hydrogen in materials’ microstructures and their site-specific dependencies.
Perspectives
The discussions in this work highlight a significant gap between the theoretical frameworks of hydrogen embrittlement mechanisms and their experimental validation. Like many scientific domains, theoretical developments in metallurgy often outpace the experimental methods available to test, confirm, or refuse them. The principle of falsifiability, crucial to scientific inquiry and the growth of scientific knowledge, mandates the immediate study and efforts to be oriented to the new experimental methodologies capable of probing the effects of hydrogen in materials at the nanoatomic scale.
