Heat treatment changes the internal structure of metals in ways that directly affect hardness, toughness, ductility, wear resistance, and fatigue life. Whether working with steel, aluminum, titanium, or specialty alloys, manufacturers rely on metallurgical microscopy to verify that heat-treated materials meet performance specifications and quality standards. From grain size evaluation to phase ide …

Food Packaging Seals under the Microscope Microscope World recently worked with a customer that needed to view the quality of their sealant on food packaging. In particular they needed to see the seal of a potato chip bag. A metallurgical microscope was used along with a camera with extended depth of focus software (also known as z-stacking software). Below are the images that were captured of the …

What is Fiberglass? Fiberglass is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet, or woven into fabric. It is a strong, lightweight material that is chemical and heat resistant. On its own fiberglass will easily break. However, when fiberglass has a core of something between it, the material becomes very strong. Pound for po …

What are the Different Microscope Types and Their Uses? There are a number of different types of microscopes and each of them solves unique problems. Below you will find information on the five different microscope types along with the applications for each microscope and just who might use each instrument. Below each description of the microscope and its use is an image that was captured using th …
