ADVANCED MATERIALS & PROCESSES | OCTOBER 2024 26 extent. Excessively high alloy composition may not bring additional technical benefit but will almost certainly increase system costs. The best approach for material selection is to understand hydrogen impacts. As a simplified method based on technical understanding and business consideration, material selection criterion, such as, Nieq values of 27, can be a good engineering design tool. ~AM&P Acknowledgments Sincere gratitude to Swagelok colleagues Cyprian Illing, Michael Bestic, and Buddy Damm for their valuable inputs and discussions.

ASM HANDBOOK VOLUME 10: MATERIALS CHARACTERIZATION The 2019 edition of ASM Handbook, Volume 10: Materials Characterization provides detailed technical information that will enable readers to select and use analytical techniques that are appropriate for their problem. Each article describing a characterization technique begins with an overview of the method in simplified terms and lists common applications as well as limitations. The articles also describe materials characterization in general terms according to material type and serve as a jumping off point to the more specific technique articles. asminternational.org Print: $380 / ASM Member: $285 ISBN: 9781627082112 Product Code: 05918G ASM Digital Library: $102 / ASM Member: $79 EISBN: 978-1-62708-213-6 ASM Digital Library price is for one-year single user access.
