Quantification of the Dislocation Density, Size, and Volume Fraction of Precipitates in Deep Cryogenically Treated Martensitic Steels

open access: yesMetals, 2020
Two groups of martensitic alloys were examined for changes induced by deep cryogenic treatment (DCT). The first group was a range of binary and ternary compositions with 0.6 wt % carbon, and the second group was a commercial AISI D2 tool steel.

Identification of Cementite Newgrowths Near Triple Boundary Grain Intersection in Spheroidized Heat-resisting Pearlitic Steel

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2017
The microstructure of pearlitic steel 12Х1МФ spent its servis life has been investigated by the microscope Neofot - 32. To identify the cementite grain and carry out its elemental analysis was used the multipurpose scanning electron microscope ЕVO - 50 c

Austenite formation kinetics from multicomponent cementite-ferrite aggregates [PDF]

open access: yes, 2020
Metastable austenite strongly influences the mechanical properties of many advanced high strength steels (AHSS) and its formation kinetics during intercritical annealing strongly depend on the initial microstructure.

The Effect of Hot-Mounting on the Microstructure of an As-Quenched Auto-Tempered Low-Carbon Martensitic Steel

open access: yesMetals, 2019
The effect of hot-mounting for metallographic studies of as-quenched low-carbon martensitic steels has been studied. Hot-mounting is typically carried out at 150–200 °C, i.e., a low-temperature tempering regime. Cold- and hot-mounted specimens

Mechanism of Layer Formation during Gas Nitriding of Remelted Ledeburitic Surface Layers on Unalloyed Cast Irons

open access: yesMetals, 2023
Unalloyed cast iron materials exhibit low tribological and corrosive resistance. In this respect, nitriding has a wide range of applications for steels. In the case of cast iron, the advantageous properties of nitrided layers are impaired by the presence

Synchrotron strain scanning for residual stress measurement in cold-drawn steel rods

open access: yes, 2011
Cold-drawn steel rods and wires retain significant residual stresses as a consequence of the manufacturing process. These residual stresses are known to be detrimental for the mechanical properties of the wires and their durability in aggressive ...

Controlling the formation of reverted globular austenite and the as-transformed austenite grain size in low-alloy steel based on cementite

open access: yes工程科学学报, 2023
Austenite reversion has been widely used in the traditional heat treatment of steels, and recently, it has been used in the fabrication of advanced high-strength steels.

Nitrogen diffusion through cementite layers

open access: yes, 2010
International audienceMassive cementite layers with a time-dependent thickness were grown on ferrite substrates by nitrocarburising in a dedicated NH3/H2/CO/N2 containing gas atmosphere at 783 K, 823 K and 843 K.

Improvement in the Strength–Ductility Balance of Tempered Martensite Steel by Controlling Cementite Particle Size Distribution [PDF]

open access: yes, 2023
We attempted to improve the strength–ductility balance of tempered martensite steel by controlling cementite particle size distribution. Four types of samples of varying tempering temperatures were prepared: T973-60m and T823-60m samples were heated to ...
