Thermodynamic Prediction of the Liquidus, Solidus, and Ae3 Temperatures, and Phase Compositions for Low-alloy Multicomponent Steels
The vast majority of steel weld deposits solidify under highly nonequilibrium cooling conditions. A consequence of this is the chemical segregation of substitutional alloying elements during solidification, a segregation that persists as the weld cools to ambient temperature. Solidification-induced segregation of interstitials is usually not a problem due to the ease with which they can diffuse...
متن کاملGraphene nanocomposite coatings for protecting low-alloy steels from corrosion
facturing methods. Graphene nanocomposite coatings for protecting lowalloy steels from corrosion A ceramic engineer or scientist unfortunately must admit that there is an unwelcome member of the family among us—iron oxide, or rust. This unpleasant family member is disruptive at best. More often it is destructive, nearly impossible to control, and a consumer of resources that are devoted to it i...

The decomposition of austenite to ferrite or cementite begins at the equilibrium phase boundary of austenite/ (ferrite austenite) or austenite/(cementite austenite) in binary Fe–C phase diagram. The temperature values on the phase boundaries of austenite/(ferrite austenite) and austenite/(cementite austenite) at a certain carbon content are called Ae3 and Acm temperatures of the steel, respecti...
متن کاملEstimation of Atmospheric Corrosion of High-Strength, Low-Alloy Steels
This data analysis was undertaken to investigate the weatherability of steels whose compositions do not fall in the range of ASTM Standard G101, Estimating the Atmospheric Corrosion Resistance of Low-Alloy Steels (1). This standard was developed to estimate the corrosion resistance of low-alloy weathering steels from chemical composition data and from actual atmospheric exposure tests. This sta...
متن کاملEffect or Inoculation on Microstructure and Properties of Low C-Mn and Low Alloy Steels
Effect of the addition of various inoculants on the morphology and mechanical properties of low C-Mn and low alloy steel samples is studied by thermal and mechanical processing of the samples after solidification. According to the results obtained from metallographic studies with the electron microscope and microanalysis with x-rays, the distribution of inoculating agents in the steel matrix is...
