“…It is evident that two phases of ferrite and austenite in the intercritical zone (α + γ) were formed for producing DP steels at first [71]. Then, the austenite phase was transformed to the martensite phase via quenching [1,38,72]. The ferrite phase experiences a plastic strain with the occurrence of the martensitic transformation.…”

Ferritic–martensitic dual-phase (DP) steels are prominent and advanced high-strength steels (AHSS) broadly employed in automotive industries. Hence, extensive study is conducted regarding the relationship between the microstructure and mechanical properties of DP steels due to the high importance of DP steels in these industries. In this respect, this paper was aimed at reviewing the microstructural characteristics and strengthening mechanisms of DP steels. This review article represents that the main microstructural characteristics of DP steels include the ferrite grain size (FGS), martensite volume fraction (MVF), and martensite morphology (MM), which play a key role in the strengthening mechanisms and mechanical properties. In other words, these can act as strengthening factors, which were separately considered in this paper. Thus, the properties of DP steels are intensely governed by focusing on these characteristics (i.e., FGS, MVF, and MM). This review article addressed the improvement techniques of strengthening mechanisms and the effects of hardening factors on mechanical properties. The relevant techniques were also made up of several processing routes, e.g., thermal cycling, cold rolling, hot rolling, etc., that could make a great strength–ductility balance. Lastly, this review paper could provide substantial assistance to researchers and automotive engineers for DP steel manufacturing with excellent properties. Hence, researchers and automotive engineers are also able to design automobiles using DP steels that possess the lowest fuel consumption and prevent accidents that result from premature mechanical failures.

“…2 The materials employed as SHTP must be resistant to thermal shock and chemically stable due to operation above 800 • C. 3 However, the materials used for SHTP in CSP systems are usually refractory steels such as austenitic, martensitic, and nickel-based alloys. [4][5][6] These alloys have poor resistance to oxidation and thermal shock at 800-1000 • C, resulting in unstable CSP operation. 7 Although nickel-based alloys can operate at temperatures above 800 • C for extended periods of time, technological immaturity and high prices have limited their large-scale manufacture.…”

Corundum‐mullite composite ceramics appropriate for application in solar heat transmission pipelines were fabricated by the addition of Tm2O3 and sintered at atmospheric pressure. The results demonstrated that with the introduction of Tm2O3 (1–7 wt.%), the physical and mechanical properties, corrosion resistance, and thermal shock resistance of the composite ceramics were significantly enhanced. The sintered sample AT5 (with 5 wt.% of Tm2O3 added) showed the best overall performance at 1550°C. The residual bending strength remained higher than 186 MPa after corrosion with 20 wt.% H2SO4 solution and 10 wt.% sodium hydroxide solution. The reaction of Tm2O3 with the Al2O3–SiO2 system produced the Tm2O3–Al2O3–SiO2 liquid phase. This liquid phase eliminated the pores through viscous flow, resulting in a dense microstructure. Furthermore, more mullite and dithulium disilicate were generated after thermal shock cycles, and their inhibition of crack deflection and extension allowed the composite ceramics to achieve excellent thermal shock resistance (residual bending strength as high as 199 MPa). The prepared corundum‐mullite composite ceramics have a good potential for application in solar heat transmission pipelines.
