The isothermal transformation kinetics, microstructure, and mechanical properties of a 0.23C high silicon steel, which is isothermally treated both below and above the martensite start temperature (Ms) are investigated. Results show that the small amount

Kinetics of mechanochemical transformations
Physical Chemistry Chemical Physics, 2020To help understanding the mechanisms underlying mechanochemical transformations, we propose a kinetic model that relates macroscopic and microscopic scales while accounting for the statistical nature of the mechanical processing of powder.

In the above, a phase transition was viewed as resulting from changing a control parameter, such as T or p, across a phase boundary, say a coexistence line, of the system’s phase diagram. In practice, such a transformation, of say a liquid phase into a crystal phase, will however require a considerable amount of molecular scale reorganization, and this

Investigation of microstructural evolution and bainite transformation kinetics of multi-phase steel
Materials Science & Engineering: A, 2020In this study, multi-phase steel with a mixture of ferrite, bainite, retained austenite and martensite is obtained after specific heat treatments, which include intercritical annealing, isothermal holding and final quenching.

Transformation kinetics for nucleus clusters
Acta Materialia, 2009Abstract A rigorous mathematical approach based on stochastic geometry concepts is presented to extend previous Johnson–Mehl, Avrami, Kolmogorov treatment of transformation kinetics to situations in which nuclei are not homogeneously located in space but are located in clusters.

Nucleation and growth transformation kinetics
Physical Review B, 1995As a result of the reassessment of the Kolmogorov-Johnson-Mehl-Avrami (KJMA) theory for the kinetics of nucleation and growth transformations, an integral-equation formulation has been developed instead of the well-known and widely used Avrami equation.

Transformation kinetics of retained austenite in the tensile Lüders strain range in medium Mn steel
Scripta Materialia, 2019Medium Mn steel usually exhibits Luders banding behavior accompanied with austenite-to-martensite transformation during deformation. In tensile tests with standard samples, Luders front exhibits steep gradients in thickness and strain, which brings ...
