Aluminum testing presents unique metallographic challenges due to the metal’s soft and ductile nature. The material is prone to deformation-induced damage during preparation and requires specialized techniques to achieve accurate, reliable results. The surface forms a protective oxide layer after preparation, making subsequent etching especially difficult. Proper specimen preparation is essential whether you’re conducting aluminum […]
In terms of mounting metallographic samples, the introduction of phenolic thermosetting plastics in ’28 completely changed the face of the industry, by giving us a reliable way to encase the specimens, though initially, it wasn’t exactly sophisticated. Coming into the ’50s, castable resins took the industry to new levels, and enabled us to adjust the […]
