the effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. in this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. the results were the minimum interlamellar spacing of 35 nm and maximum ulti...

In this study, we performed scanning transmission X-ray microscopy with a spatial resolution of approximately 50 nm to investigate the two-dimensional mapping chemical states carbon in Fe–C alloy. The lamellar texture (pearlite) consisting ferrite (α-Fe) and θ-Fe3C an interval 100 was identified by absorption from 1s→2p excitation image. It clearly observed that there exist more than two types ...

The effect of stress and strain on the transformation kinetics of pearlite is investigated by phase-field simulation. Strain is considered in terms of expansion/contraction during transformation and due to concentration gradients in austenite. It is demonstrated that due to the concentration dependence of the eigenstrain, an inhomogeneous stress distribution ahead of the transformation front en...

In this study, structural and crystallographic properties of phase transformations in Fe–Mn– Mo–Si (Mn = 15.14 wt.% 18.45 wt.%) alloys were investigated. The effects heat treatment temperature on microstructure investigated by Scanning Electron Microscopy (SEM) Metallurgical (MM). addition to this, revealed using Transmission (TEM) X–Ray Diffraction (XRD) methods. the samples subjected at 750 ...
