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…

The impacts of porosity in additively-manufactured (AM) specimens on mechanical properties are well-known. In this webinar, NSL’s Director of Technology Development, Dr. Dave van der Wiel, will discuss the various techniques commonly used to characterize the porosity and density of AM bodies. You will learn how scientists draw conclusions by analyzing and interpreting resulting data….

A failure is when a part does not perform as the customer expects, or the part fails an internal test. Metallurgical failure analysis can be a valuable tool for determining what the next step should be to solve a problem. This webinar will highlight particular metallurgical tests that may be performed in failure analysis such…

In contrast to conventional static funnel flow techniques, dynamic avalanche rheometry can generate highly reproducible data that correlates very well with various metal powder properties. The technique is included in several joint ISO/ASTM work items and an ASTM interlaboratory study, reflecting the drive toward standardization of new powder flow techniques. This webinar reviewed the use…

If a part does not perform as it is expected to, Metallurgical Failure Analysis may be a valuable tool for solving the problem. In this first webinar of our two-part series, you will learn what failure analysis is and how it is performed. What to Expect from a Metallurgical Failure Analysis: Overview This webinar has…

Advancements in technology and techniques have improved dramatically since gas adsorption began being used to measure the surface area of materials in particle form over 80 years ago. In our upcoming webinar, you will better understand the latest technology and findings, the physical significance of surface area in particle systems, and the potential effects in…

The aerospace industry is increasingly adopting metal additive manufacturing (AM) for both flight safety-critical aircraft parts and non-critical flight parts. The approach offers a shorter development cycle, which means products can be developed quicker and design changes easily incorporated. Similar to other 3D-printing methods, metal AM, specifically select laser melting (SLM) and electron-beam melting (EBM), builds up a part…
