“…These observations were in line with the previous works. 28,30,31 In addition, the existence of carbides acted as crack arrestors and enhanced the crack resistance. The residual stresses induced by thermal expansion during multi-pass welding and its subsequent contraction during solidification aided the fracture in the weld region.…”

“…29 The volume of dimples depends upon the density of dislocations. 30 Under high-stress regimes, the crack propagation will be quick, and fracture occurs suddenly while the crack propagation is slow under low-stress regimes. A ductile mode of fracture is noticed for all BM specimens, and plastic deformation occurs prior to fracture followed by the initiation of voids and coalescence to form cracks.…”

This work investigates the fatigue performance of 10 mm AISI C1018 low carbon steel plates welded with ER70S-6 using a gas metal arc welding-based spin-arc welding process. Welded joint microstructure is characterized by bainite, acicular ferrite, and allotriomorphic ferrite along with pearlite in the ferritic matrix. The tensile strength of the weld metal was comparable with base metal and meets the mechanical property requirements in accordance with the ASTM A311/A311M-04 (2020) standard. The fatigue strengths of base metal and weld metal are 121 and 126 MPa, respectively, after sustaining 106 cycles. During cyclic loading, fracture surfaces were distinctly noticed as the crack initiation, crack propagation, and final rupture regions. The decrease in alternating stress increased the fatigue cycles to final rupture, and the nature of fatigue fracture was ductile with dimples and voids.

“…This exposure led to an increase in fatigue life due to the increase in the yield strength and resistance to rupture and a reduction in the elastic modulus. The authors in [ 23 ] also observed an increase in the fatigue life of 35CrMo steel exposed to a magnetic field of 1.2–1.3 T of 10–15%. The authors of [ 24 ] associated the significant (more than three-fold) increase in the fatigue life of EN8 steel and AA2014-T6 alloy treated by a variable magnetic field of 0.54 T with the growth of residual compressive stresses in the near-surface layers of both metals as a result of the treatment.…”

Influence of Constant Magnetic Field upon Fatigue Life of Commercially Pure Titanium

et al. 2022

Cyclic tests of the multicycle fatigue of commercially pure titanium were performed under normal conditions (without a magnetic field) and after exposure to a constant magnetic field of varying density (B = 0.3, 0.4, 0.5 T). It was shown that the application of the constant magnetic field of varying density led to a fold increase in the average number of cycles to destruction of the VT1-0 titanium samples by 64, 123, and 163%, respectively. Scanning electron microscopy revealed that the magnetic field led to a 1.45-fold increase in the critical length of the fracture (the width of the fatigue crack growth zone) and a 1.6-fold decrease in the distance between the fatigue striations in the accelerated crack growth zone of the destroyed titanium samples. It was established that a subgrain (fragmented) structure formed in the area of the fatigue growth of the fracture of the titanium samples. The size of the subgrains corresponded to the spaces between the fatigue striations, which had an inhibitory influence on the microcrack propagation. Collectively, the revealed facts are indicative of a higher material resistance to fatigue fracture propagation and increased operation resources under the fatigue tests in the magnetic field, which correlates with the data on the growth of the average number of cycles to fracture of the VT1-0 titanium samples.

An Enhanced Lemaitre Model and Fracture Map for Cr5 Alloy Steel during High-Temperature Forming Process

et al. 2022

View full text Add to dashboard Cite

To effectively control and predict crack defects in the high-temperature forming process of Cr5 alloy steel, based on the traditional Lemaitre damage model, a new high-temperature damage model of Cr5 alloy steel was proposed which considered the change of material elastic modulus with temperature, the influence of material hydrostatic pressure as well as temperature and strain rate on material damage. Because Cr5 alloy steels are usually forged at high temperatures, tensile testing is an important method to study the damage behaviour of materials. Through the high-temperature tensile test and elastic modulus measurement test of the Cr5 alloy steel, the stress–strain curves and the relationship curves of the elastic modulus value with the temperature of Cr5 alloy steel under different temperatures and strain rates were obtained. A new high-temperature damage model of Cr5 alloy steel was built by introducing the Zener–Hollomon coefficient considering the influence of temperature and strain rate. The established high-temperature damage model was embedded in Forge® finite element software through the program’s secondary development method to numerically simulate the experimental process of Cr5 alloy steel. Comparing the difference between the displacement–load curves of the numerical simulation and the actual test of the tensile process of the experimental samples, the correlation coefficient R2 is 0.987 and the difference between the experimental value and the simulated value of the tensile sample elongation at break is 1.28%. The accuracy of the high-temperature damage model of Cr5 alloy steel established in this paper was verified. Finally, the high-temperature damage map of Cr5 alloy steel was constructed to analyse the variation law of various damage parameters with the temperature and strain rate of the high-temperature damage model of Cr5 alloy steel.
