The Proceedings includes research from the symposium held at the Conference of Metallurgy & Materials on recent advances in materials and manufacturing technologies designed for harsh and extreme service environments.  The papers presented in this volume reflect the breadth and interdisciplinary nature of research in this rapidly evolving field. They cover a wide range of topics, including high-performance alloys, ceramics, composites, coatings, and multifunctional materials with enhanced environmental resistance; innovative manufacturing technologies such as additive manufacturing, hybrid processing, advanced joining, and digital process control; process optimization; microstructural engineering and advanced materials characterization. The proceedings also include research on the design, modeling, and multiscale simulation of materials subjected to coupled extreme loading conditions, together with studies focused on testing, qualification, structural integrity, degradation mechanisms, and performance evaluation for both established and emerging engineering applications. This work highlights the importance of interdisciplinary collaboration between academia, research organizations, and industry in developing practical engineering solutions that address current and future challenges associated with harsh-service environments. 

Metallurgists have been active in CIM since its inception in 1898. In 1945, the Metallurgy Division was formed to reflect the group’s technical interests. MetSoc has grown to become one of the premier global organizations serving the international metallurgy and materials community. Its annual Conference of Metallurgy & Materials (COM) is a preeminent event on the international metallurgy meeting calendar. In partnership with sister societies, MetSoc is also a lead organizer of key world-class conference series such as Nickel-Cobalt, Copper and Lead-Zinc.
