Comparative Study of Hydrogen Embrittlement in Additively Manufactured and Wrought 316L Stainless Steel

This research project explores how different manufacturing methods affect the durability of 316L stainless steel when exposed to hydrogen, a critical factor for the safety and reliability of future hydrogen infrastructure. The study compares conventional metal processing with two advanced additive manufacturing techniques, Wire Arc Additive Manufacturing (WAAM) and Laser Powder Bed Fusion (LPBF), to see how each influences the materials resistance to hydrogen embrittlement, a type of damage that can cause metals to become brittle and break. By producing and testing identical samples using consistent methods in both Canada and Australia, the project will generate valuable insights into how microstructure impacts performance in hydrogen-rich environments. This collaboration between UBC Okanagan and the University of Sydney combines world-class fabrication and testing facilities, contributing to safer clean energy systems. The results will help guide engineers and industry leaders in choosing the best materials and production methods for hydrogen-related applications, while also supporting international research training and innovation in both countries.
