TL;DR: In this article, a bimetallic steel bar (BSB) consisting of stainless steel (cladding layer) and carbon steel (substrate) is proposed for reinforced-concrete (RC) structures.
Abstract: For reinforced-concrete (RC) structures in a corrosive environment, corrosion tends to occur in the reinforcement, which has a significant adverse effect on the durability. Increasing the corrosion resistance of the reinforcement can substantially enhance the durability of RC structures. Therefore, a bimetallic steel bar (BSB) consisting of stainless steel (cladding layer) and carbon steel (substrate) is proposed. Considering that earthquakes are common natural disasters, load-bearing RC elements with corrosion issues may be subjected to seismic loads. For accurately predicting the seismic resistance of RC structures in service, it is useful to investigate the low-cycle fatigue performance of corroded reinforcements. To address this issue, the tensile and low-cycle fatigue performance of BSBs was investigated experimentally. An electrochemical accelerated corrosion test was conducted to obtain BSB specimens with predetermined corrosion ratios. The corrosion morphologies of the BSB specimens were studied. The mechanical and failure performance was evaluated via the tensile coupon test. The test results indicated that an increase in the corrosion ratio led to a reduction in the tensile performance of the BSB specimens. Predictive equations were proposed for the corroded BSB specimens. After the low-cycle fatigue test, the hysteresis loops of the BSB specimens were obtained, which indicated that corrosion adversely affected the low-cycle fatigue performance. Predictive equations were proposed for determining the number of cycles to failure and the total energy dissipation of the corroded BSB specimens. Increasing the corrosion ratio significantly shortened the steady stages of the maximum tensile and compressive loads. According to the results for the failure performance of BSB specimens with different corrosion ratios under low-cycle fatigue loading, increasing the corrosion ratio reduced the area of the fracture development zone and increased the area of the fracture zone.

TL;DR: In this paper, the authors showed that the martensitic transformation of the heat-affected zone (HAZ) of the C45 substrate was considered the main factor contributing to cracking of the coating.
Abstract: FeCoNiCrAl high entropy alloys (HEAs) are regarded as promising coating materials for traditional steel. However, the brittle nature always contributes to the cracking of the equiatomic FeCoNiCrAl HEA coating. In this work, FeCoNiCrAl coatings on C45 carbon steel and 304 stainless steel (304SS) pipes were fabricated using extreme high-speed laser cladding (EHLA) with a cladding speed of 50 m/min. The results showed the high-hardness character of the two coatings on C45 and 304SS substrates. The C45 substrate showed a remarkable effect on the cracking of the coating. The martensitic transformation of the heat-affected zone (HAZ) of the C45 substrate was considered the main factor contributing to cracking of the coating. The finite element method showed that the martensite transformation of C45 expanded the volume and increased the hardness of the HAZ. This restricted the plastic deformation of the substrate and increased the tensile stress and cracking tendency of the coating. As a martensitic transformation did not occur in 304SS, the low-hardness substrate effectively relieved the tensile stress in the coating and avoided cracking.
