Explore the fascinating history and industrial impact of hydrogen embrittlement in this episode of the Engineering Understood podcast from TWI Ltd. Host Sophie Hobbs is joined by Paul Woollin to break down TWI’s pivotal research, challenges, and future developments in the field.
Here’s what you’ll learn in this episode:
- The basics of hydrogen embrittlement and why it matters for industries using metals.
- Key moments in TWI’s 80-year journey with hydrogen embrittlement, including early work on Liberty Ships and weld testing methods.
- How real-world industrial challenges, such as oil and gas failures, shaped breakthrough research and standards for hydrogen embrittlement prevention.
- The shift in focus over the decades from heat affected zones to weld metals, and the evolving understanding of microstructural features linked to embrittlement.
- Modern developments, including applications in the hydrogen economy, challenges with new materials like additively manufactured alloys, and why ongoing collaboration and simulation are critical for the future.
