Describe one method for manipulation of microstructure and mechanical Essay

Describe one method for manipulation of microstructure and mechanical properties for each of the following class of materials - Essay Example This technique makes the metal soft, and it can be cut and shaped more easily. For example, mild steel is usually heated to a red heat, after which it is allowed to cool slowly. Other metals like aluminium melt when heated to high temperatures. Therefore, care must be taken when annealing them. Annealed metals can be changed to any shape and size, and then allowed to cool slowly into their hard status (Groover, 2010 p57). Nanotechnology is the process of engineering functional systems at the molecular scale usually at the Subatomic level (American Ceramic Society, 2009 p123). It usually deals with structures of 100 nanometers or less. Its main purpose is to make materials cleaner, lighter and more prà ©cised. Ceramics is one of the areas where nanotechnology has led to the production of a wide array of materials with distinct performance and property. Nano ceramics exist in solid form ranging in the size of nano meters (10-9) to micrometers (10-6). A Large number of particles provide a large surface area which can be held together by Nanokote to give stronger, light weight, brittle and thermal resistance ceramics (American Ceramic Society, 2009 p134). Mould manipulation of polymers can help in overcoming mechanical and aesthetic weaknesses that are associated with the standard injection moulding (Rudd & Long, 1997 p98). This can involve improving bulk properties like weld lines or manipulating orientation morphology enhancement. In this process, experimental outcomes of a rotating pin at the weld line of glass and talc filled polypropylene are introduced (Rudd & Long, 1997 p98). Talc filled material ensures that pin rotation speed does not exceed 100 rotation per minute, and this enhances polymer strength. Glass filled material also enhances strength significantly, but not as compare to talc filled material. Mould Manipulation technique also introduces the chances of producing other
