“…However, on the other hand, the segregation of cerium atoms at dislocations could improve the resistance of dislocation movement, inhibit migration [ 16 ] and enhance yield strength. In addition, cerium can cause large lattice distortion [ 22 ] because of the large atomic radius, which can induce solid-solution strengthening. This phenomenon is caused by the trade-off between these factors.…”

Energetic structural materials play an important role in improving the damage performance of future weapons. To improve the energy-releasing behavior, Al0.5NbZrTi1.5Ta0.8Cex high-entropy alloys were prepared by vacuum-arc melting. The results showed the presence of BCC and FCC phases in the alloy with dendritic-morphology-element segregation and there were significant dislocations in the alloys. The current study focused on the effects of cerium content on the dynamic compressive mechanical and energetic characteristics. Cerium doping enhanced the energy-releasing characteristics of high-entropy alloys. The severity of the reaction increased with the increase in the cerium content, while the dynamic compressive strength generally decreased with the increase in cerium content. The Al0.5NbZrTi1.5Ta0.8Ce0.25 showed excellent mechanical and energy-releasing characteristics. The ballistic experiments indicated that Al0.5NbZrTi1.5Ta0.8Ce0.25 can penetrate 6-millimeter A3 plates and ignite the cotton behind the target at a velocity of 729 m/s, making it an ideal energetic structural material.

“…Since that time, study on the relevance of pitch microstructure or its constituent qualities has expanded the use of equipment related to kin and nanotechnology, including as Scanning Electron Microscopes (SEM), Atomic Force Microscopes (ATM), and X-ray Diffraction (XRD) [10][11][12]. The tensile strength of the steel fibers must be more than 1000 MPa [13]. The steel fibers must be of a durable, low-carbon kind.…”

Porous asphalt composition is frequently used for the surface extraction layer of pavements because to its open structure and high air void percentage, which lessens disturbance and offers protection during precipitation. Porous asphalt composition has a high air void percentage. This would make it possible for water to be stored horizontally inside the pavement layer as well as moved about within that layer. It is possible that this may lessen the impacts of splash and spray, hence improving drivers’ sight during rainstorms. On the other hand, because to the large percentage of air voids contained inside it, the porous asphalt would be prone to rutting, cracking, and peeling. The goal of this research is to explore the microstructure of porous asphalt that has been mixed with steel fibers in proportions ranging from 0 percent to 0.3 percent. The second objective was to analyze the long-term deformation of porous asphalt that had either 0 or 0.3 percent steel fiber content. In this study, a porous asphalt composition was developed with the help of Marshall mix design. Using sieve analysis, the whole mixture of coarse, fine, filler, bituminous binder, and a range of aggregate sizes was separated into its component parts. Pictures taken using a scanning electron microscope (SEM), an energy dispersive x-ray (EDX), an x-ray diffractometer (XRD), and a fourier transform infrared spectrometer (FTIR) are being used in this inquiry (FTIR). The findings point to the possibility that the performance of porous asphalt mixture might be greatly improved by the addition of steel fiber. Additionally, one may make the case that steel fiber has a longer lifespan than the several other forms of fiber that are used in porous asphalt pavement.

“…Simultaneously, it acts to refine the grain size and bolster the yield strength. [ 14 ] Geng et al [ 15 ] found that the transformation of Al 2 O 3 inclusions in high‐strength low‐alloy steel into smaller‐sized Ce 2 O 2 S and CeAlO 3 inclusions, significantly refining the as‐cast grain. Furthermore, the small Ce 2 O 2 S inclusions can effectively promote the heterogeneous nucleation of δ‐ferrite, corroborated by Ji et al [ 16 ] Huang et al [ 17 ] undertook an extensive examination of the modification process of oxide inclusions in H13 steel with varying Ce content.…”

The effects of Ce treatment on the inclusion evolution and impact toughness of as‐cast transformation‐induced plasticity (TRIP) steel are systematically investigated by scanning electron microscope (SEM) and impact toughness testing. The results reveal that in Fe‐2Mn‐1.5Al‐1Si‐0.2C steel without Ce, the primary inclusions consist of AlN, MnS, and Al2O3. After Ce addition, the inclusions evolve into Ce‐Al‐O, Ce2O2S, CeS, and Ce2O3 inclusions. The evolution of inclusions exhibits an initial reduction in both quantity and size with increasing Ce content, followed by a subsequent increase. In cases of excessive Ce content, there is an observable rise in the overall inclusion count, marked by the emergence of CeAs, CeP, and CeC2 inclusions. The segregation model suggests that P‐containing inclusions predominantly precipitate in the late solidification process, while As‐ and C‐containing inclusions form during the solid phase. When the Ce content reaches 0.0075 wt%, the minimum values of the number density and average diameter are 96.7 mm−2 and 1.6 μm, respectively. Furthermore, the influence of the size, morphology, quantity, and type of inclusions on the impact toughness are analyzed. The highest recorded impact energy is 6.8 J with a Ce content of 0.0075 wt%.
