“…The identification of FexCa1−xCO3, which is an intermediate compound between CaCO3 and FeCO3, is obtained based on the XRD results of Esmaeely et al [8]. The Ca1.11Mn0.89(CO3)2 identified in the corrosion scale may be related to the dissolution of MnS in X100 pipeline steel [22,23]. As XRD cannot detect the amorphous phase or trace amounts of crystalline structures, XPS was tested to precisely analyze the valence states of elements in the corrosion scales.…”

The influences of Mg2+ and Ca2+ on the short-term (1800 s) corrosion behavior of X100 pipeline steel were investigated in a sodium chloride (NaCl) solution saturated with CO2. Either Ca2+ or Mg2+ in the solution inhibited the short-term corrosion of X100 pipeline steel, with the corrosion current density decreasing from 262.4 μA cm−2 to 163.5 μA cm−2 or 80.8 μA cm−2. During longer-term (8−48 h) immersion, the Mg2+ inhibited the formation of the protective scale, whereas the Ca2+ accelerated the formation of the scale. Further, an experimental equation establishing the relationship between the precipitation rate of the corrosion scale and the exposure time was proposed to quantitatively study the effects of Mg2+ and Ca2+ on the precipitation rate of the corrosion scale.

“…Despite the use of special technological methods of soft reduction, electromagnetic mixing, introduction of macrocoolers into the axial zone of a continuously cast billet, etc., it is not possible to completely prevent the development of segregation processes. It is known that the formation of certain types, including glassy non-metallic inclusions at the final stages of ladle processing during the continuous casting of steel, leads to a significant inhibition of heat and mass transfer processes and, accordingly, the development of segregation processes during steel crystallization [101][102][103].…”

High-strength micro-alloyed steels are widely used in various branches of technology and industry due to the simultaneous combination of high indicators of strength, ductility, fatigue, corrosion resistance, and other service properties. This is achieved due to the reasonable choice of the optimal chemical composition and parameters of temperature deformation treatment of steel that provide a synergistic effect on the dispersed microstructure and characteristics of excess phase precipitates, which control the achievement of these difficult-to-combine properties of rolled products. Additionally, the improvement of the level and stability of these properties, as well as the prevention of the occurrence of defects, is largely determined by the indicators of the homogeneity of the composition, structure by volume and manufacturability of the metal, and primarily hot ductility, which are controlled by the presence of precipitation of excess phases, including micro-alloying elements. In accordance with the circumstances noted, in the present review, a generalization, systematization, and analysis of the results of the studies are conducted on the effect of phase precipitates on the hot ductility and homogeneity of composition and structure, depending on the chemical composition and parameters of the temperature-deformation treatment of steel.
