Modeling the Mechanical Response of a Dual-Phase Steel Based on Individual-Phase Tensile Properties

Metals, 2020
In this work, the engineering stress–strain tensile curve and the force-deflection bending curve of two Dual-Phase (DP) steels are modeled, combining the mechanical data of fully ferritic and fully martensitic steels.

Fine-grained dual-phase steels fabricated via cold-rolling ferrite-martensite structure and subsequent intercritical annealing

Journal of Materials Research and Technology, 2023
A proposed alternative method for processing dual phase (DP) steels is the utilization of a cold-rolled duplex ferrite-martensite structure, followed by intercritical annealing.

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

Effect of Nb on the microstructure and mechanical properties of a hot-rolled dual-phase steel produced by TMCP

High Temperature Materials and Processes
Nb microalloying is of significance to the grain refinement and mechanical properties of DP steels. In the present study, two DP steels without/with addition of Nb were produced by the TMCP process and the effect of Nb on the microstructure and ...

The Effect of NbC Precipitates on Hydrogen Embrittlement of Dual-Phase Steels

Metals
New grades of dual-phase (DP) steels with ultimate tensile strength (UTS) up to 1500 MPa have been developed using a continuous annealing process. This study investigates the effects of over-aging temperature and NbC precipitates on the microstructure ...

Effects of DP steel microstructure on the disappearance of discontinuous yielding

MATEC Web of Conferences, 2018
Although in terms of quality is not as high as TRIP steel, DP steel has been developed as an option to meet the minimum standard industrial requirement for automotive. Steel development for automotive material leads to posses high strength without suffering its ductility and weld ability, in addition there is no appearance of discontinuous yielding ...

The Influence of Martensite on Line Broadening in Neutron Diffraction Spectra of a DP Steel.

ISIJ International, 2002
Neutron diffraction experiments were performed on dual-phase steels to determine the feasibility of measuring the martensite volume fraction through ferrite peak broadening. Mechanical properties were also investigated to determine if a correlation exists with ferrite peak broadening.

Bioinspired Mechanically Robust Organic–Inorganic Hybridized Bio‐Adhesives With up to 50% Inorganic Components by Bi‐Continuous Phase Engineering

Advanced Functional Materials, EarlyView.
A robust plant protein adhesive was prepared by fabricating a bi‐continuous organic–inorganic hybrid structure. Compared with traditional organic–inorganic hybrid adhesives, the addition amount of inorganic phase is increased from 0.2%–3.0% to 50%, and the strength and toughness are increased by 6 and 121 times, respectively.
