Tech Talk Webinar: Moisture Analysis by Karl Fischer Titration

Even very low levels of moisture can have significant impacts on metal powder flow, consolidation and surface oxidation, particularly during powder reuse. In this webinar, we examine how Karl Fischer titration is applied to precise moisture analysis in metal powders for additive manufacturing. Although several techniques can be applied to the measurement of water in…

Famous Failures Webinar: Hydrogen Embrittlement

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…

Famous Failures Webinar: Fatigue in Transportation

Fatigue has always been a major issue in designing for transportation, particularly airplanes. This webinar presented three airplane failures from NTSB and British Ministry reports that were the result of fatigue: the DeHavilland Comets in 1954, Aloha 243 in 1988, and Southwest 1380 in 2018. It also included a brief discussion of fatigue and a…

Famous Failures: Stress Corrosion and the Silver Bridge Failure

Stress corrosion cracking is a progressive cracking mechanism that can often lead to catastrophic failure. There have been several notable failures due to this phenomenon, such as the collapse of the Silver Bridge in December of 1967. Learn about this failure in the first webinar of our “Famous Failures” series, as well as the metallurgy…
