What is Ferrite,Cementite,Pearlite ,Martensite,Austenite

Austenite It is a solid solution of iron-carbon which is stable only within a particular range of composition and temperature,and is non-magnetic.On cooling below 700 austenite formation in c35 and c45 alloys request pdf#176;C it is completely transformed into ferrite which is magnetic and cementite to form the eutectoid pearlite,together with free ferrite or free cementite,depending on whether Transformation Behavior of Supercooled Austenite during Austenite Formation in C35 and C45 Alloys p.4637.Cold Workability and Magnetic Properties of 6% Si Steel p.4643.Interactions between Recrystallisation and Phase Transformations during Annealing of Cold Rolled Nb-Added TRIP-Aided Steels Request Permissions Share References [1] H.Yada,C.M.Li and H.Yamagata ISIJ Int.,40(2000),200 The Role of Nucleation Behavior in Phase-Field Simulations Three-dimensional (3-D) phase-field simulations of the austenite () to ferrite () transformation during continuous cooling at different cooling rates were performed for an Fe-0.10C-0.49Mn (wt pct) steel,with the aim of studying the interaction between the assumed nucleation temperature range and the effective interfacial mobility when fitting transformation kinetics curves.
