Hydrogen embrittlement can cause a part to fail under stresses well below the expected material strength. Plus, the phenomenon is virtually undetectable using current NDE techniques. In this “Famous Failures” webinar, NSL metallurgists Rebecca Stawovy and Ben Schmidt explore a Bell 222U Helicopter failure that occurred due to hydrogen embrittlement. They discuss which conditions can lead to hydrogen embrittlement, how it causes a part to fail, and how it can be prevented.
