FAQ: What are the microstructural constituents Austenite, Martensite, Bainite, Pearlite and Ferrite?Frequently Asked Questions Austenite and ferrite Austenite was originally used to describe an iron-carbon alloy, in which the iron was in the face-centred-cubic (gamma-iron) form. It is now a term used for all iron alloys with a basis of gamma-iron. When iron carbon alloys transform from austenite on cooling, the solubility limit of carbon in ferrite is commonly exceeded. Pearlite Pearlite is usually formed during the slow cooling of iron alloys, and can begin at a temperature of 1150°C to 723°C, depending on the composition of the alloy. Martensite Martensite is formed in steels when the cooling rate from austenite is sufficiently fast. Beres and Beres  stated that their formulae were within 40°C of the actual Ms , in all cases studied, whereas other formulae had larger scatter bands. Models combining the kinetics of martensitic transformation with mechanics, in view of microstructural development are also applicable. Bainite References

Led by the University of Liverpool, MATTER was originally one of over 70 different projects funded by the Teaching and Learning Technology Programme (TLTP). This phase of the project resulted in the publication in 1996 of the award-winning Materials Science on CD-ROM, with a second version being released in 1998. More recently, our activities have expanded to include the development of science-based software resources for schools, industry and other science disciplines in universities. In 2001 we started a new project, aluMATTER, with the European Aluminium Association to develop interactive e-Learning materials for aluminium science and technology. In 2001, we also started a pilot project with the International Iron and Steel Institute (IISI) to create similar resources for steel science and technology.
