WebMay 5, 2024 · Pearlite is a harder and stronger but machinable microconstituent. Increasing amounts of pearlite in the matrix increases the hardness and strength of the iron. The intermediate strength grades of malleable are normalized (air quenched) and tempered to have a pearlitic matrix. The high strength grades are liquid quenched and tempered … WebDesignation A602 − 94 (Reapproved 2014) Standard Specification for Automotive Malleable Iron Castings1 This standard is issued under the fixed designation A602; the number immediately following the de[.] - 123doc - thư viện trực tuyến, download tài liệu, tải
Pearlite is a two-phased, lamellar (or layered) structure composed of alternating layers of ferrite (87.5 wt%) and cementite (12.5 wt%) that occurs in some steels and cast irons. During slow cooling of an iron-carbon alloy, pearlite forms by a eutectoid reaction as austenite cools below 723 °C (1,333 °F) (the eutectoid temperature). Pearlite is a microstructure occurring in many common grades o…
WebStandard or ferritic malleable iron is satisfactory for use as a cast, soft magnetic material. It is made by heat-treating white iron. In addition to its magnetic properties, it can be readily cast into intricate shapes and is one of the most machinable ferrous metals. By merely changing the heat-treatment, pearlitic or martensitic malleable iron can be produced from … jlm the storeWebTraductions en contexte de "iron (cast iron" en anglais-français avec Reverso Context : cast-iron, graphite cast iron, cast-iron excuse, cast-iron alibi, malleable cast iron.
