A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a sharp snapping sound. When used in materials science, it is generally applied to materials that fail wh… WebCeramic. Another example of brittle material is ceramic.

WebQuasicrystals are exceptionally brittle. They have few dislocations, and those present have low mobility. Since metals bend by creating and moving dislocations, the near absence of dislocation motion causes brittleness. On the positive side, the difficulty of moving dislocations makes quasicrystals extremely hard. They strongly resist deformation. WebOct 10, 2024 · It is rather hard and brittle. To make it softer, some proportion of a plasticizer has to be added when it's hot and malleable. In the last century, the plasticizer was in general dinonylphthalate. It works well, but it is a bit volatile. So after a couple of years, the plasticizer gets evaporated, and the polymer becomes brittle again.

Brittle failure can occur at temperatures below the DBTT. Therefore, low DBTTs are preferred to be used as structural materials.

WebFigure 10.37 The entities of a solid phase may be arranged in a regular, repeating pattern (crystalline solids) or randomly (amorphous). Metals and ionic compounds typically form ordered, crystalline solids. Substances that consist of large molecules, or a mixture of molecules whose movements are more restricted, often form amorphous solids.
