PREDICTION OF CRITICAL STRESS AND STRAIN FOR THE ONSET OF DYNAMIC RECRYSTALLIZATION IN PLAIN CARBON STEELS
The aim of the present study is the prediction of critical conditions (including critical strain and flow stress) for the initiation of dynamic recrystallization during thermo-mechanical processing of plain carbon steels. For this propose, torsion tests were conducted at different temperature (1050, 1100 and 1150˚C) and strain rates (0.002, 0.02 and 0.2/s). All flow curves showed a peak st...
متن کاملSome phase transformations in steels
About 70% of all the steel compositions that are currently used have been developed within the last 10 years. Novel iron alloys are being conceived, manufactured, and marketed with a regularity which has confounded many prophecies. Phase transformation theory has contributed to the successful development of steels. This overview will begin therefore with a discussion of the atomic mechanism by ...
متن کاملVariation of Transition Temperatures from Upper to Lower Bainites in Plain Carbon Steels
Experimental results and explanations for the transition temperature from upper to lower bainites in carbon steels containing from 0.20 to 1.80 wt%C were presented metallographically and kinematically. The experimental results are summarized as follows: I) Lower bainite is not formed in steels with less than 0.35 wt%C and no transition from upper to lower bainite occurs. 2) The transition tempe...
متن کاملSTRAIN INDUCED AUSTENITE-TO-FERRITE TRANSFORMATION BEHAVIOR OF PLAIN CARBON STEELS THROUGH SINGLE PASS ROLLING
In principal, a proper combination of strength and ductility is achieved through micro component refinement in steels. This is particularly empowered with ferrite refinement down to micron sizes in ferrite pearlite engineering steels. The latter is achieved through various well-defined methods in which strain induced transformation (SIT) has shown spectacular capabilities. In the present study,...
متن کاملModelling of Simultaneous Transformations in Steels
The microstructure of a steel is often developed by solid-state transformation from austenite. The major transformation products are allotriomorphic ferrite, pearlite, Widmanstätten ferrite, bainite and martensite, differentiated by morphological features, and their nucleation and growth mechanisms. A steel often consists of several phases as a result of dynamic evolution during continuous cool...
