2Forming gas — is a mixture of up to 10% hydrogen in nitrogen. It is sometimes called a dissociated ammonia atomosphere due to the reaction which generates it::2 NH3 → 3H2+ N2Forming gas is used as an atmosphere for processes that need the properties of… …
3Température de transition vitreuse — Article connexe : Transition vitreuse. Au passage de la Tg, le module de Young des élastomères varie considérablement En termes de propriétés physiques, la température de transition vitreuse (Tv, anglais : Tg) d une matière est souvent… …
4Vacuum forming — Vacuum forming, commonly known as vacuforming, is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto or into a single surface mold, and held against the mold by applying vacuum… …
5Spray forming — Spray forming, also known as spray casting, spray deposition[1] and in situ compaction,[2] is a method of casting near net shape metal components with homogeneous microstructures via the deposition of semi solid sprayed droplets onto a shaped… …
6Ceramic forming techniques — are ways of forming ceramic shapes. This can be used to make everyday tableware from teapots, to engineering ceramics such as computer parts. Methods for forming powders of ceramic raw materials into complex shapes are desirable in many areas of… …
7Cold forming — or cold forging, is a manufacturing process in which metal is shaped at ambient temperature to produce metal components to a close tolerance and net shape. Techniques include bending, cold drawing, cold heading, coining extrusion (forward or… …
8Flow forming — is a metal forming technique in which a disk or tube of metal is formed over a mandrel by a roller using tremendous pressure. The roller shears the metal, forcing it against the mandrel, creating the shape and width of the final product. [… …
