The role of time-temperature path on the isothermal austenite-to-bainite phase transformation of low alloy 51 CrV 4 steel was investigated and the corresponding microstructures were analyzed. The important finding is that an incomplete initial austenitization treatment leaves undissolved carbides in the matrix, such that lower carbon and chromium content in the matrix result, eventually accelerating the phase transformation. Furthermore, the residual carbides constitute additional nucleation… 
On the bainitic and martensitic phase transformation behavior and the mechanical properties of low alloy 51CrV4 steel
The role of the austenitization treatment (austenitizing temperature and austenitizing time) on the subsequent phase transformation behavior of low alloy 51CrV4 steel was investigated. The results
Evolution of transformation plasticity during bainitic transformation
Abstract The influences of prior austenitization treatment and the state of applied stresses on the evolution of transformation plasticity strains during isothermal bainitic phase transformation and
On the effect of plasticity on the kinetics of the isothermal bainitic transformation
Forging processes are accompanied by large plastic deformations and residual stresses. Depending on the local cooling rate the deformed material typically is in the stable or the supercooled
A Comparative Analysis of Austenite-to-Martensite and Austenite-to-Bainite Phase Transformation Kinetics in Steels
This paper presents a comparison of the macroscopic transformation strain evolution as a function of the bainite and martensite phase fractions in steels. Specifically, the evolution of anisotropic
Non-isothermal austenitic transformation kinetics in Fe–10Cr–1Co alloy

Functional Gradation of Low Alloy Steel by Differentially Controlled Phase Transformation
In the present study, the phase transformation behaviour of 51CrV4 steel was investigated both in an actual flange forming process and under idealized isothermal bainitic transformation conditions.
Micromechanical modelling of stress-assisted martensitic transformation
A computational micromechanics study of stress-assisted martensitic transformation using finite elements is carried out within a thermomechanical framework including the aspect of plastic
Stress-affected transformation to lower bainite
Experiments have been conducted on the formation of lower bainite under the influence of an externally applied stress. It was found that both the ferritic and cementite components of the
