Interpretation of the microstructure of steels - University of …
When the austenite in such steels is cooled, ferrite first forms in the Mn-depleted regions. Ferrite has a very low solubility for carbon which partitions into the Mn-enriched regions which on …
Austenite Martensite Bainite Pearlite and Ferrite structures
Delta ferrite is the high temperature form of iron, formed on cooling low carbon concentrations in iron-carbon alloys from the liquid state before transforming to austenite. In highly alloyed …

Alpha Ferrite - Microstructure and Properties - Nuclear Power …
Ferrite or α-ferrite is a body-centered cubic structure phase of iron that exists below temperatures of 912°C for low concentrations of carbon in iron. The primary phase of low-carbon or mild …
Acicular ferrite - Wikipedia
Acicular ferrite is a microstructure of ferrite in steel that is characterised by needle-shaped crystallites or grains when viewed in two dimensions. The grains, actually three-dimensional in …
Ferrite-Bainite - AHSS Guidelines
Ferrite-Bainite (FB) steels are hot rolled steels typically found in applications requiring improved edge stretch capability, balancing strength and formability. The microstructure of FB steels …
