The proposed project aims to enhance knowledge in natural sciences and engineering through the characterization of domestically produced high-strength steels, which are critical for polar-class icebreakers. Centered on the CSA400 structural steel grade supplied by Algoma Steel Inc., the program will assess its mechanical properties, with particular emphasis on performance in sub-zero temperatures and resistance to brittleness. Furthermore, the study will optimize welding techniques, including flux-cored arc welding (FCAW) and submerged arc welding (SAW), to ensure structural integrity and durability. Partnering with industry leaders Chantier Davie Canada Inc. (CDCI) and Algoma Steel Inc., the program integrates academic and industrial expertise to enhance shipbuilding capabilities for Arctic conditions. Through comprehensive material characterization, welding optimization, and industrial collaboration, the research aims to bolster Canada's position in sustainable shipbuilding, promote economic growth, and ensure environmental sustainability in the Arctic. This initiative promises significant economic, environmental, and societal benefits, reinforcing Canada's leadership in global shipbuilding and Arctic development. Additionally, the program will facilitate the use of domestic steel grades, fostering economic growth, supporting the steel production cycle, and creating job opportunities. Moreover, it will contribute to the development of scientific knowledge in materials characterization, welding, and icebreaker construction, with findings disseminated through journal and conference publications, enriching the global scientific community. Furthermore, the program will provide multidisciplinary training for eight Highly Qualified Personnel (HQPs), equipping them for competitive employment opportunities.
