However there are several ways to differentiate between the two: Brittle fracture leaves a bright and shiny surface, but ductile fracture is dark and dull Brittle fracture leaves a rough, coarse and grainy surface, but ductile fracture is fine, stringy and smooth Brittle fracture leaves radial ridges and chevrons, but ductile fracture leaves shear lips To prevent brittle fracture, you can: Use fine-grained, clean, tough and hardenable steel (high nickel, molybdenum and low chrome, manganese, carbon, phosphorus and silicon contents) Reduce the load, flaws and tensile stress on the teeth Avoid running at temperatures lower than the transition temperature of the steel To prevent ductile fracture, you can: Reduce load Make the teeth thicker (this distributes the load) Avoid edges and corners since cracks usually start on these Choose a material with a high yield strength and no brittle inclusions Bending fatigue is another common failure mode
