“…This leads to protruded cementite lamellae because of the dissolution of side-by ferrite lamellae, and these protruded cementite plates later break down due to burst waves during cavitation, allowing the progress of the damage. This matches well with the observation by Katiyar et al [21] during dynamic polarization of differently cooled steels of the same composition, where the dissolution of ferrite is greater in the case of coarse pearlite than finer pearlite. This also leads to higher dissolution and thus cavitation damage in the case of the furnace-cooled and the as-received steels as indicated by the depth of attack shown in Fig.…”

“…The signature of quasi-pearlite has not been observed in the case of the furnace-cooled steel. The probability of the formation of quasi pearlite increases in the following order: as-received, air-cooled, and forced-air-cooled [21] . The presence of quasi-pearlite also endorses the enhanced hardness of the air-cooled as well as the forced-air-cooled steel.…”

“…The near eutectoid steel (0.71% C, 0.24% Si, and 1.14% Mn) as selected in this work is mainly used in manufacturing Indian rail. This steel is usually of pearlitic microstructure [20] , and is also used in other structural applications, like springs, high strength wires, and locomotive tires [21] . In this regard, the interlamellar spacings of the pearlite in rebar steel can be modified using different cooling rates after austenitization, and subsequently, its mechanical and corrosion behavior can change significantly [22] , [23] .…”

“…This transformation can lead to a different electrochemical behavior that might affect the structure stability if not properly considered [26][27][28]. For instance, the different phases in steel can promote microgalvanic couples that will promote enhanced corrosion kinetics [29,30]. Some researchers have worked on studies of structural steels after simulated-fire exposure, however, further research is still needed [31].…”

In this study the effect of thermomechanical treatments in chloride induced pitting corrosion is presented for carbon steel rebars exposed to synthetic fly ash (FA) pore solution. Due to the likely phase transformations that steel reinforcements in concrete experience during the event of a fire, the understanding of the corrosion behavior of such phases is key in predicting the stability of the structure. The motivation for this study arrives from the scarce literature regarding the corrosion behavior of thermomechanically treated steel reinforcements in FA environments and the need for further investigation to understand its mechanism. In order to better understand the effects on the corrosion behavior electrochemical measurements including cyclic potentiodynamic polarization curves (CPP) and electrochemical impedance spectroscopy (EIS) were used. It was found that quenched specimens showed enhanced corrosion kinetics as their icorr values were higher, being of 3.18 × 10−5 and 2.20 × 10−5 A/cm2 for water and oil quenched compared to 2.13 × 10−6 A/cm2 for the as-received. Furthermore, the effective capacitance of the double layer (Ceff,dl) showed the lower stability of the passive film for the quenched specimens, with values of 1.11 × 10−3 µF/cm2 for the as-receive sample that decreased to 8.12 × 10−4 µF/cm2 for the water quenched sample. The anodic charge transfer coefficient in the synthetic FA alkaline pore solution changes from 0.282 to 0.088, for the as-received and water quenched rebars specimens, respectively. These results indicate a lower energy barrier for the anodic dissolution reaction of quenched specimens, indicating that martensite and bainite microstructures promote corrosion process. Enhanced corrosion was found on quenched samples presenting martensite and bainite microstructure as showed by the increased pith depth, with values of 5 μm compared to 1 μm observed in the as-received samples.

“…Most M2 steel is still manufactured by the conventional method which uses sand molds [17]. With the development of metallurgical technology in recent years, the production of M2 steel has been realized by adopting continuous casting in some advanced steel mills [18]. The cooling rate of sand mold casting is slower than that of continuous casting.…”

AISI M2 steel was smelted in a 150 kg medium-frequency induction furnace and cast to form round billets with a cross-section diameter of 100 mm via a vertical continuous caster and sand mold. The secondary dendrite arm spacing (λ2), cooling rates, permeability and size and distribution of grains and network carbides of the two billets were studied. The results show that the continuous casting process can effectively decrease the λ2 value, permeability and size of the grains and carbides and improve the distribution of the grains and carbides during solidification. The λ2 values of the billets cast with a sand mold and continuous caster are 37.34 μm and 21.14 μm, respectively, and the cooling rate is 3.6 K·s−1 and 12.0 K·s−1, respectively. The area fractions of carbides at the center of the billets cast with the sand mold and continuous caster are 0.24 and 0.16, respectively, and increase by 27.7% and 25.4%, respectively, compared with their average values. The average grain size of billets cast with the sand mold and continuous caster is 69.4 μm and 50.5 μm, respectively. Compared with the sand mold billet, the grain size at the center of the continuous casting billet is reduced by 25.5%. The relationship between the grain size and cooling rate is presented in this paper.
