Athermal Martensite Transformation Curve [PDF]

open access: yesMaterials Research, 2016
In a recent paper, the present authors [Materials Research. 2015. 18(3): 595-601] demonstrated that the thickness of athermal martensite plates had a thermally activated component. The reason for this was probably the interaction of the athermal glissile

Discontinuous lath martensite transformation and its relationship with annealing twin of parent austenite and cooling rate in low carbon RAFM steel

open access: yesMaterials & Design, 2021
Lath martensite transformation in low carbon steel relates to the discontinuity of the transformation rate, which exhibits a series of martensite transformation rate maxima (peaks), especially in low cooling rates. In the present work, we put an emphasis

Carbon content-tuned martensite transformation in low-alloy TRIP steels. [PDF]

open access: yesSci Rep, 2019
Ultrahigh strength and good ductility are obtained for two low-alloy transformation-induced-plasticity steels fabricated by the quenching and partitioning (Q&P) processing, respectively.

Kinetic models of multiple-stage martensite transformation and subsequent isothermal bainite formation excluding ε-carbide precipitation in intercritical quenching and partitioning steels

open access: yesMaterials & Design, 2019
The kinetic models of multiple-stage martensite transformation and subsequent isothermal bainite formation were investigated in intercritical quenching and partitioning steels. The modified K-M model that considering instantaneous kinetic characteristics

Dislocation densities in a low-carbon steel during martensite transformation determined by in situ high energy X-Ray diffraction

open access: yesMaterials Science & Engineering: A, 2021
The evolution of the dislocation densities in martensite and in austenite during the quench of a low-carbon (0.215 wt% C) steel is investigated in situ by the mean of a High Energy X-Ray Diffraction experiment on a synchrotron beamline.

Martensite’s Logistic Paradigm

open access: yesMaterials Research, 2021
This work introduces a deterministic approach to the martensite transformation curve. Martensite is a nucleation-controlled transformation that has two characteristics: autocatalysis and auto-accommodation.

Understanding ferrite deformation caused by austenite to martensite transformation in dual phase steels

open access: yes, 2021
During the production of DP steels, the volume expansion and shape change accompanying the austenite to martensite transformation is accommodated by the deformation of surrounding ferrite grains. The extent of the deformation in ferrite grains ultimately

Shape Memory Alloys (Part I): Significant Properties [PDF]

open access: yesKemija u Industriji, 2014
Shape memory alloys (SMAs) belong to a group of functional materials with the unique property of “remembering” the shape they had before pseudoplastic deformation.
