“…All specimens for mechanical tests such as tensile tests and hardness measurement are austenized at 840°C for half an hour, followed by oil quenching, and finally by tempering at 170°C for 3 h. Details on tensile testing and hardness measurement have been reported elsewhere 18–20 . The fracture surfaces are examined by scanning electron microscopy (SEM, ZEISSEVO18 and Hitachi S4300) with an energy dispersive X‐ray (EDX) analyzer to investigate the corresponding property‐related microstructural features 21,22 and surface morphology 23,24 . Inclusion parameters, such as the inclusion type, size, and distribution, are quantitatively analyzed by an ASPEX inclusion analyzer.…”

A new double vacuum melting route (conventional second refining + vacuum arc refining [CSR + VAR]) with 33% lower production cost than the traditional VIM + VAR route has been tried. Compared with the CSR route, the CSR + VAR route reduces the average inclusion size from 27.1 ± 12.3 μm to 13.7 ± 2.4 μm, and the CSR + VAR steel processes a 13.1% higher rotatory bending fatigue (RBF) fatigue strength (σ À1 ) and a 3-timeslonger RCF L 10 life.The crescent-shaped granular bright facet (GBF) zone, normally found in high-strength steels' very high cycle fatigue regimes beyond 10 7 cycles normally under a much lower stress amplitude, appears around inner inclusions on the CSR + VAR steel RBF fracture surfaces in high cycle fatigue regimes beyond 3 Â 10 5 cycles. The development of GBF zones is estimated to account for 79%-90% of the RBF fatigue life. The average crack propagation rate (da/dN) for GBF zones varies from 1.3 Â 10 À12 m/cycle to 24 Â 10 À12 m/cycle and increases with the stress amplitude.

“…Dislocations-phase interface interactions play an important role for structural metals, in not only the strength [ 136 , 137 ], but also other mechanical properties such as ductility and toughness [ 138 ], wear resistance [ 139 ], fatigue properties [ 140 , 141 , 142 , 143 ] and micro-pitting [ 144 ], as well as the properties of heterogeneous structures [ 145 , 146 , 147 ]. All these need the systematic investigations with exquisitely designed experiments and/or simulations.…”

The interactions between dislocations (dislocations and deformation twins) and boundaries (grain boundaries, twin boundaries and phase interfaces) during deformation at ambient temperatures are reviewed with focuses on interaction behaviors, boundary resistances and energies during the interactions, transmission mechanisms, grain size effects and other primary influencing factors. The structure of boundaries, interactions between dislocations and boundaries in coarse-grained, ultrafine-grained and nano-grained metals during deformation at ambient temperatures are summarized, and the advantages and drawbacks of different in-situ techniques are briefly discussed based on experimental and simulation results. The latest studies as well as fundamental concepts are presented with the aim that this paper can serve as a reference in the interactions between dislocations and boundaries during deformation.
