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

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 ...

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

Cementite Formation in CH4-H2-Ar Gas Mixture and Cementite Stability.

open access: yesISIJ International, 2001
Iron ore reduction/cementation by CH 4 -H 2 -Ar gas (35vol% CH 4 , 55vol% H 2 and 10 vol% Ar) was examined in a fixed bed reactor in the temperature range of 600-925°C. Iron oxides were first reduced to metallic iron and then iron was carburised to cementite.

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
