Modelling the Microstructure of Martensitic Steels
A method based on the kinetics of crystal growth has been developed and applied to the computation of three-dimensional microstrucuture in austenite-matensite steels. The detailed crystallography of the transformation is used to model a realistic martensitic microstrucuture during the transformation without an external system of stresses. The interaction energy based on the plastic work model i...
متن کاملStrength of 10CR-N martensitic steels
lOCr stainless steel has been employed to examine the effect of nitrogen on microstructure and strength. Applying Solid state gaseous nitrogenising treatments a whole range of nitrogen martensite structures containing up to 0.45 wt% were obtained. It was found that a linear relationship exists between strength and nitrogen content in precipitate free martensitic structures. Yield strength incre...
متن کاملSuper Plasticity of /α Duplex Stainless Steels
In this paper the studies of the two-phase super Plasticity stainless steels is studied. The aim of this study obtained the suitable criteria to thermo-mechanical treatment condition for decrease the microstructure (grain size) and super plasticity property in two-phase stainless steels. Also here we want to show the appropriate ranges of temperature and strain rate used in the process super pl...
متن کاملDriving force for martensitic transformation in steels
recently determined LVl~ to be 111918 J mol-I at temperatures below 1000 K, and pointed out that their experimental data were free from various 'intercept effects' which had dogged earlier investigations. Similarly, for T<1000K, they deduced '\~s=51.44Jmol-IK-I. There seem to be no data on the variation of LVl~ or ,\~s as a function of x. However, Lobo and Geigerl found that LVll: and ,\S~S do ...
متن کاملMicrostructure and cleavage in lath martensitic steels
In this paper we discuss the microstructure of lath martensitic steels and the mechanisms by which it controls cleavage fracture. The specific experimental example is a 9Ni (9 wt% Ni) steel annealed to have a large prior austenite grain size, then examined and tested in the as-quenched condition to produce a relatively coarse lath martensite. The microstructure is shown to approximate the recen...
