Bainite formation and deformation behavior in an intercritically annealed Fe-1.0Mn-0.09C steel

The microstructure, tensile response and fracture behavior of a high-performance structural steel: influence of orientation

“…The high-strength steels are particularly noted for offering an attractive combination of high tensile strength, acceptable to good fracture toughness and improved weldability coupled with better performance in environments spanning a range of aggressiveness, to include both aqueous and gaseous, when compared one-on-one with the mild steel counterpart. [1][2][3][4][5][6][7][8][9][10] The production and processing, to include both primary and secondary, of the family of highstrength steels have culminated from noticeable advances in both the processing and manufacturing techniques currently in use in the steel industry, especially in the domain of thermomechanical processing. In particular, a careful control of heating and subsequent mechanical deformation processes during production of the steel can result in the formation of a fine grain size end product.…”

Influence of Cyclic Straining on Fatigue, Deformation, and Fracture Behavior of High-Strength Alloy Steel

“…The mechanical properties of the family of new and improved family of high-strength steels are governed by the conjoint and mutually interactive influences of chemical composition, processing history, intrinsic microstructural features, temperature of operation, loading rate, and even potential constraints at the crack tip (Ref [19][20][21][22][23][24][25][26][27][28][29]. Prevailing conditions that are often favorable for minimizing crack tip constraints are also conducive for both enabling and enhancing the ability of the ''candidate'' steel to be receptive to plastic deformation.…”

Critical isothermal temperature and optimum mechanical behaviour of high Si-containing bainitic steels

“…Higher the stability of the retained austenite, indicated by the lowering of M S temperature renders the possibility of getting optimum mechanical properties. Choi et al [28] have also studied a low carbon (0.09 wt% C) steel and shown the same observation of maximum enrichment of retained austenite pool at 623 K and thus, leading to the best mechanical properties at this temperature. However, the importance of M S temperature has not been understood.…”
