In this episode, Jennifer Larimore and Avery Boyer, Materials Engineers at Chemours, join co-hosts Heather Allain and Marc Cook to share an inside look at how a materials lab works. Jennifer and Avery walk through the step-by-step process of analyzing samples—from sectioning, cleaning, reviewing documentation and photographing through the final wrap up of documenting and communicating findings to the customer. They discuss analysis methods like nondestructive evaluation, XRF identification, hardness, fracture testing, polishing and metallography to uncover critical material properties. The discussion also explores the importance of turning technical findings into clear, actionable recommendations. Throughout the conversation, the guests highlight how these practices help solve real-world challenges, prevent failures, and ensure long-term reliability.

In this episode, Cathleen Shargay, Advisor of Materials and Welding Engineering at Becht, joins co-hosts Heather Allain and Marc Cook to explore the complexities of materials selection during project execution. The conversation covers a wide range of essential topics, from understanding what materials selection diagrams (MSDs) are and how they interface with process engineering, to evaluating life cycle cost inputs and establishing design life. Cathleen also unpacks how MSDs relate to Integrity Operating Windows (IOWs) and Corrosion Control Documents (CCDs), and how these tools work together to support informed decision-making. The episode dives into strategies for managing excursions, assessing corrosion circuits, and understanding the consequences of material failure. Finally, the discussion looks ahead to how artificial intelligence is beginning to shape materials selection and analysis in the future of engineering.
