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…

In this second installation of our Famous Failures webinar series, attendees learned about the role of heat in the failure of the steel in the World Trade Center buildings on September 11, 2001. This webinar featured Dave Kovarik, NSL Metallurgist and Failure Analyst, George Vander Voort, president of Vander Voort Consulting with 29 years of…

At NSL, we are honored to have our article “How Metal Powder Surface Area Influences Additive Manufacturing” published in Powder Metallurgy Review Magazine. The article explains why the knowledge of powder surface area is a critical parameter in the metal Additive Manufacturing process. Learn more about wet chemistry in the highly-respected publication below. Then, contact…

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…

Microwave Extraction Provides More Reliable Analysis of High Mass Unit Additives Microwave extraction has proven to be both an efficient and cost-effective testing method for RoHS compliance. Please fill out the form below to access the White Paper:

With nearly 1,000 materials restricted by California’s Proposition 65, compliance may appear to be a daunting and expensive task. In this Tech Talk webinar, NSL’s Dave van der Wiel and Sarah Baskerville discuss common misconceptions of Prop 65 compliance, review the regulated products and materials, and provide practical advice for helping businesses navigate toward a…

Optical microscopy has been a staple of metallurgical analysis to determine cleanliness, grain structure, surface conditions, porosity, and more. In this Tech Talk webinar, NSL metallurgists Dave Kovarik and Rebecca Stawovy explain the history of metallurgical microscopes and how they work. You will also learn the features of modern-day microscopes and how they are used…

The analysis of particle size distributions is widely accepted as a critical requirement in many metal and ceramic processes. In this webinar, we discussed the pragmatic issues associated with the most readily-available techniques and which complementary methods might be insightful for certain applications, without having to develop a new historical dataset of particle size information….

NSL’s Scanning Electron Microscope (SEM) is a very useful tool for examining materials at up to 100,000x magnification. In this webinar, you will enjoy a first-hand presentation and demonstration of NSL’s remote SEM capabilities to learn how it can be used in examining fracture surfaces, surface chemical analysis, and more. NSL metallurgists Rebecca Stawovy and…
