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

Quenching and tempering of steel - tec-science

웹2024년 4월 7일 · The aim of this work was to develop a novel bainitic steel that will be specifically dedicated to achieving a high degree of refinement (nano- or submicron scale) along with increased thermal stability of the structure at elevated temperatures. The material was characterized by improved in-use properties, expressed as the thermal stability of the … 웹The term tempering refers to a heat treatment used to increase the toughness of iron-based alloys. ...

Tempering of the Bainite and the Bainite/Martensite Duplex …

웹Bainite is a type of steel that’s produced by cooling faster than pearlite but slower than martensite. Additionally, bainite has plate-shaped designs in its microstructures, while … 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 … 웹转变产物：贝氏体 B（bainite）——由过饱和F和渗碳体组成的混合物。 550~350℃：上贝氏体（upper bainite ）（B上）羽毛状组织，强度与塑性都较低，脆性很高。 350℃~ Ms：下贝氏体（lower bainite ）（B下）针片状组织，综合性能好。 3）马氏体转变（又称低温转变） ledbury casual shirts adon
