Impact of Martensite Spatial Distribution on Quasi-Static and Dynamic Deformation Behavior of Dual-Phase Steel

Crack Propagation Behavior of Impact Fracture in Case Hardening Steel Subjected to Combined Heat Treatment with Excess Vacuum Carburizing and Subsequent Induction Hardening

“…There were researches of crack bending along the prior austenite grain boundary [8][9][10][11][12][13] and crack bending and branching due to heterogeneous microstructure such as dual phase steel having α and α'. [14][15][16][17][18] Ohta et al 19) observed the propagation path of the fatigue cracks using a specimen in which θ orientation was aligned by rolling the high-carbon steel. They reported that the crack showed bending and branching when the crack encountered θ, resulting in the decrease of the stress intensity factor and suppression of crack propagation.…”

Microstructural Characteristics and Strengthening Mechanisms of Ferritic–Martensitic Dual-Phase Steels: A Review

“…The range of strength and ductility of DP steels can be extended as compared to other generations of AHSSs via the One of the well-known and outstanding members of AHSSs is DP steel [8,12,[18][19][20]. Although DP steels are placed in the first generation of AHSSs, as shown in Figure 1 [8], extensive research is still being conducted regarding AHSSs [21][22][23][24][25]. The behavior of DP steels has exhibited that these steels are significantly competitive with newer generations of AHSSs (i.e., second and third generation) [1,2,13,26].…”
