This Buehler seminar will cover a variety of issues encountered in both metallograhy and hardness testing of ferrous materials, including common problems and how to avoid them. The webinar will delve into fundamental considerations for a wide variety of steel and stainless materials, coatings, heat and surface treatments. This includes efficiency, quality, cost savings, etching for microstructure and accuracy/reproducibility in hardness testing. The webinar is aimed at metallurgical technicians, engineers and others who carry out metallographic preparation of aerospace materials. A recording of the webinar will be available after the event.
