WebFeb 26, 2011 · Carbides, nitrides, and carbonitrides have great influence on the properties of steel but are relatively little studied at a fundamental level: experimentally because of small dimensions of the precipitates and other difficulties, theoretically because of complex structures and poorly defined compositions. WebJun 15, 2015 · All Ti-, Zr- and Hf-based carbides and nitrides have a simple NaCl-type crystal structure with two sublattices: a metal atom sublattice and a non-metal atom sublattice. The non-metal atom sublattice can normally accommodate up to 50% of vacancies [2] leading to severe off stoichiometry. WebThe solubility of nitrides and carbides in the liquid phase, austenite and ferrite has been evaluated. ...

"In physics, the terms “order” and “disorder” indicate the presence or absence of symmetry in a multi-particle system. In condensed matter physics, systems are typically ordered at low temperatures. However, when heated, they undergo one or more phase transitions into less ordered states. " - Order and disorder in carbides and nitrides
