Analysis of the relationship between microstructure and mechanical properties of intercritically annealed 3.5Mn steel

open access: yesMaterials Research Express, 2021
The paper mainly studies intercritically annealed medium manganese steel, which only contains 3.5 wt% Mn. After annealing at different temperature, the microstructure of the experimental steel is composed of ferrite and austenite with different ...

Analysis and simulations of multifrequency induction hardening [PDF]

open access: yes, 2013
We study a model for induction hardening of steel. The related differential system consists of a time domain vector potential formulation of the Maxwell's equations coupled with an internal energy balance and an ODE for the volume fraction of {\sl ...

Thermal Stability of Retained Austenite and Properties of A Multi-Phase Low Alloy Steel

open access: yesMetals, 2018
In this work, we elucidate the effects of tempering on the microstructure and properties in a low carbon low alloy steel, with particular emphasis on the thermal stability of retained austenite during high-temperature tempering at 500–700 °C ...

Giant magnetocaloric effect in isostructural MnNiGe-CoNiGe system by establishing a Curie-temperature window [PDF]

open access: yes, 2013
An effective scheme of isostructural alloying was applied to establish a Curie-temperature window in isostructural MnNiGe-CoNiGe system. With the simultaneous accomplishment of decreasing structural-transition temperature and converting antiferromagnetic

A Novel Design to Eliminate Lüders Band in Medium-Mn Steel and Its Microstructure-Property Relationship

open access: yesCrystals, 2023
In the current work, we design a novel medium Mn steel with a superior mechanical property and no Lüders band. For industrial applications, a “low Mn addition” chemical composition and two kinds of different annealing processes with various initial ...

Nudged-elastic band method with two climbing images: finding transition states in complex energy landscapes [PDF]

open access: yes, 2014
The nudged-elastic band (NEB) method is modified with concomitant two climbing images (C2-NEB) to find a transition state (TS) in complex energy landscapes, such as those with serpentine minimal energy path (MEP).

Towards the ab initio based theory of the phase transformations in iron and steel [PDF]

open access: yes, 2017
Despite of the appearance of numerous new materials, the iron based alloys and steels continue to play an essential role in modern technology. The properties of a steel are determined by its structural state (ferrite, cementite, pearlite, bainite ...

Origin of stabilization of macrotwin boundaries in martensites [PDF]

open access: yes, 2011
The origin of stabilization of complex microstructures along macrotwin boundaries in martensites is explained by comparing two models based on Ginzburg-Landau theory. The first model incorporates a geometrically nonlinear strain tensor to ensure that the
