TTT Diagrams and Heat Treatment of Steel Metallurgy
Bainite is a plate-like microstructure that forms in steels at temperatures of 125–550 °C (depending on alloy content). First described by E. S. Davenport and Edgar Bain, it is one of the products that may form when austenite (the face-centered cubic crystal structure of iron) is cooled past a temperature where it is no longer … 더 보기 In the 1920s Davenport and Bain discovered a new steel microstructure which they provisionally called martensite-troostite, due to it being intermediate between the already known low-temperature 더 보기 • Free textbooks devoted to bainite, all three editions. • The Alloying Elements in Steel, by Edgar C. Bain • Overview of Bainite in multiple languages 더 보기 Above approximately 900 °C a typical low-carbon steel is composed entirely of austenite, a high-temperature phase of iron that has a cubic close-packed crystal structure. On cooling, … 더 보기 With increasing bainite content in steel, the hardness, yield and tensile strength remain almost constant for bainite content up to 50%, and then increase by ca. 30%. Hence meter-size shafts and plates of high-bainite steels have been commercially mass … 더 보기 웹Bainitic hardening, quenching and tempering (intermediate process) To achieve the required bainite structure, the workpiece is quenched in a warm salt bath after the austenitizing … 웹2.10.4.4 Tempering of bainite.
