Sintering or frittage is the process of compacting and forming a solid mass of material by pressure [1] or heat [2] without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms/molecules in the sintered material diffuse across the ...
NPTEL is the largest e-repository in the world of courses in engineering, basic sciences and selected humanities and management subjects. [1] The platform and materials have been jointly developed by Indian Institutes of Technology (IITs) and Indian Institute of Science. [2] The initiative is funded by the central Ministry of Education. The ...
Manufacturing engineers develop and create physical artifacts, production processes, and technology. It is a very broad area which includes the design and development of products. Manufacturing engineering is considered to be a subdiscipline of industrial engineering/systems engineering and has very strong overlaps with mechanical engineering ...
A bill of materials or product structure (sometimes bill of material, BOM or associated list) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an end product. A BOM may be used for communication between manufacturing partners or confined to a single ...
Value engineering can lead to the substitution of lower-cost materials, as with the exterior cladding that accelerated the Grenfell Tower fire in London. [1] [2]Value engineering (VE) is a systematic analysis of the functions of various components and materials to lower the cost of goods, products and services with a tolerable loss of performance or functionality.
Magnesium peroxide degrades near moisture. Alumina is water-resistant and can be fabricated to be quite strong, so in practice, most MHDs have used alumina for the insulating walls. For the electrodes of clean MHDs (i.e. burning natural gas), one good material was a mix of 80% CeO 2, 18% ZrO 2, and 2% Ta 2 O 5. [16]
Sulfur at harbor in North Vancouver, British Columbia, ready to be loaded onto a ship Latex being collected from a tapped rubber tree. A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials that are feedstock for future finished products.
dispersed phase is an organic material and the continuous phase is water or an aqueous solution and is termed water/oil (w/o) if the dispersed phase is water or an aqueous solution and the continuous phase is an organic liquid (an "oil"). Note 5: A w/o emulsion is sometimes called an inverse emulsion.
