Ultrafine-grained dual-phase maraging steel with high strength and excellent cryogenic toughness
, 2021A novel heat treatment route consisting of a low-temperature solution followed by an over-aging treatment at 500 °C is proposed to develop a high-strength, high-cryogenic-toughness maraging steel by forming an ultrafine-grained martensite (α′) and ...

A good combination of ultimate tensile strength (UTS) up to 1365 MPa and total strain to failure (StF) to 15.5 % has been achieved due to deformable martensite in the invented vanadium-microalloyed dual-phase (DP) steel, which was manufactured by two ...

Effects of the Phase Interface on Spallation Damage Nucleation and Evolution in Dual‐Phase Steel
Steel Research International, 2020The dual‐phase steel sample obtained by step quenching (SQ) of AISI 1020 steel is shock loaded using one‐stage light‐gas gun experiments. The free surface particle velocity is measured by Doppler pin system (DPS) during the loading experiment. The effect

Plastic anisotropy of dual-phase steels
International Journal of Plasticity, 1990Abstract A continuum mechanics model on yielding and plastic deformation of dual-phase steels consisting of a large number of spherical second-phase islands dispersed in a matrix has been developed. The model is based on the Hill's theory on orthogonal anisotropy and the mean internal stress arising from the differences in strengths and plastic ...

Failure Initiation in Dual-Phase Steel
Key Engineering Materials, 2013This research work aims to model the failure initiation in dual-phase (DP) steel. A microstructure based approach by means of representative volume elements (RVE) is employed to evaluate the microstructure deformation and the failure initiation on the mesoscale. In order to determine cohesive parameters for martensite cracking, a two level approach has

Nanostructured high-carbon dual-phase steels
Scripta Materialia, 2011A nanostructured dual-phase microstructure has been achieved by a quenching–partitioning–tempering treatment of a high-carbon super bainitic steel. Observations showed that the nanostructured steel consisted of fine martensite, retained austenite and carbides. The hardness reached up to approximately 700 HV1.

Hydrogen embrittlement of dual-phase steels
Metallurgical Transactions A, 1981Reversible hydrogen embrittlement (HE) is usually only found in quenched and tempered steels with yield stresses in excess of 1035 MPa (150 ksi). A study of the HE phenomena in two dual-phase steels with tensile strengths of about 690 MPa (100 ksi) has shown that these steels are susceptible to the presence of hydrogen.
