“…To meet the growing demands, researchers performed considerable works to improve the quality of bearing steel materials, including reducing impurities during smelting [7][8][9] and optimizing the microstructure [10][11][12] during rolling and heat treatment. With the ongoing efforts over centuries, the compositions and macro-defects in bearing steel can be well controlled through proper metallurgical techniques.…”

A numerical study of stress distribution and fatigue behavior in terms of the effect of voids adjacent to inclusions was conducted with finite element modeling simulations under different assumptions. Fatigue mechanisms were also analyzed accordingly. The results showed that the effects of inclusions on fatigue life will distinctly decrease if the mechanical properties are close to those of the steel matrix. For the inclusions, which are tightly bonded with the steel matrix, when the Young's modulus is larger than that of the steel matrix, the stress will concentrate inside the inclusion; otherwise, the stress will concentrate in the steel matrix. If voids exist on the interface between inclusions and the steel matrix, their effects on the fatigue process differ with their positions relative to the inclusions. The void on one side of an inclusion perpendicular to the fatigue loading direction will aggravate the effect of inclusions on fatigue behavior and lead to a sharp stress concentration. The void on the top of inclusion along the fatigue loading direction will accelerate the debonding between the inclusion and steel matrix.

“…The high tensile strength (higher than 1380 MPa) and good ductility of high strength steels mainly derived from the complex heterostructure microstructure, such as martensite, precipitate and small amount of austenite. Simultaneously, the complex heterostructures have an important impact on the corrosion resistance, involving the alloy distribution and interface of heterogeneous [3][4][5][6].…”

The high strength martensite steels are widely used in aerospace, ocean engineering, etc., due to their high strength, good ductility and acceptable corrosion resistance. This paper provides a review for the influence of microstructure on corrosion behavior of high strength martensite steels. Pitting is the most common corrosion type of high strength stainless steels, which always occurs at weak area of passive film such as inclusions, carbide/intermetallic interfaces. Meanwhile, the chromium carbide precipitations in the martensitic lath/prior austenite boundaries always result in intergranular corrosion. The precipitation, dislocation and grain/lath boundary are also used as crack nucleation and hydrogen traps, leading to hydrogen embrittlement and stress corrosion cracking for high strength martensite steels. Yet, the retained/reversed austenite has beneficial effects on the corrosion resistance and could reduce the sensitivity of stress corrosion cracking for high strength martensite steels. Finally, the corrosion mechanisms of additive manufacturing high strength steels and the ideas for designing new high strength martensite steel are explored.
