Divorced Pearlite in Steels
Steels containing large carbon concentrations are used particularly when a large hardness is required, for example in the manufacture of components such as bearings. This, however, makes it difficult to shape or machine the alloys during the process of component manufacture unless they are first heat–treated into a softened condition. One method of achieving this economically is to generate a m...
متن کاملThe effect of increasing of iron concentration on the physical properties of zinc-iron ferrite nanoparticles
In this research, zinc-iron ferrite nanoparticles were synthesized by thermal treatment method. The presence of crystalline phases by X-ray diffraction (XRD) was determined by X-ray diffraction (XRD), which confirmed the presence of crystalline phases in all nanoparticles. The particle size and morphology of the nanoparticles were obtained using Field Emission Scanning Electron Microscopy (FESE...
متن کاملDiffusion–Controlled Growth of Pearlite in Ternary Steels
A theory for the diffusion–controlled growth of pearlite in steels containing manganese is presented and assessed in the light of experimental data. Given the overwhelmingly rapid diffusivity that a substitutional solute has within the transformation front, the growth rate is found to be dominated by diffusion parallel to the interface with austenite as the rate controlling step. The relevant i...
متن کاملThe Effect of Ferrite Grain Size on the Fatigue Behavior of Ferrite-martensite Dual-phase Steels
The effect of ferrite grain size on the fatigue and tensile properties of dual phase steels with a 0.25 volume fraction of martensite (Vm) under different heat treatments was investigated. The heat treatments were homogenized at 1200 oC along with several subsequent normalizations at 910 oC, resulting in different microstructures and mechanical properties. After heat treatment, the obtained ste...
