The common organization of steel Category:

Austenite: carbon and alloy elements dissolved in γ-Fe solid solution, remains face-centered cubic lattice of γ-Fe

Features: austenitic good plasticity, low strength, has a certain toughness, not having a ferromagnetic.

Ferrite: carbon and alloy elements dissolved in a-Fe solid solution having a body-centered cubic lattice, poor ability to dissolve carbon, like ferritic stainless steel 430 nanopowder

Features: with good toughness and ductility; was bright polygonal grain structure;

Martensite: carbon dissolved in supersaturated solid solution of α-Fe, and body-centered tetragonal structure;

Common martensite forms: lath, flaky;

Lath martensite: low, medium carbon steel and stainless steel formed slats made up of many groups of mutually parallel slats composed of bundles. Shaped space Like a flat strip, a austenite grain lath can be converted into several (usually 3-5);

Plate martensite (acicular martensite): common in high carbon steel and high-Ni, Fe-Ni alloy; when the small size of the largest piece to an optical martensite. When the mirror can not tell, it is called hidden martensite. In the normal production of quenched martensite are generally hidden martensite.
