“…Figures 7 and 8 show the morphology of the S1400 and S1500 samples, respectively. According to elemental EDS, maps (Figure 7E–H; Figure 8E–H), the mass absorption coefficient of phases and based on XRD results (Figure 2), the lighter phase in the BSE images is V‐containing, MAX phases, and the darker phase is Al‐containing, Al 2 O 3 , phases 38,39 . According to the SEM images, the grain size of S1500 is higher than that of S1400, and the grain size of S1400 is higher than S1200.…”

The higher grain size of S1500, in turn, could justify the higher obtained density and the lower porosity (Table 2).…”

A 2:1:1 MAX phase, V2AlC, composited with Al2O3 is prepared using spark plasma sintering (SPS). To obtain a sample with suitable physical and mechanical properties, an especial current rate regime is carried out for SPS. Different final temperatures of the synthesis (1000, 1200, 1400, and 1500°C) are considered (named S1000, S1200, S1400, and S1500, respectively). Phase analysis, physical and mechanical properties characterizations, and morphology of the samples are performed to determine the quality of the samples. The best characterizations belong to the samples of S1400 and S1500. Bending strengths about 325 and 316 MPa are obtained for the samples of S1400 and S1500, respectively. Regarding the total MAX phases formation and strength, the optimum sample is S1400. However, regarding bulk density, wear resistance, and hardness, S1500 has an advantage over the S1400. The advantages of S1500, as well as its larger grain size, are attributed to the better sintering of Al2O3.

“…MAX phases are layered hexagonal carbides and nitrides referenced to the general formula M n+1 AX n , (MAX), where "n" ranges between 1 and 4, "M" represents a transition metal (Sc, Ti, V, Cr, etc. ), "A" is an A-group (mainly III A and IV A , or groups 13 and 14) element and "X" is either C and/or N [150,151]. MAX phase materials exhibit excellent properties of both metals and ceramics such as high electrical and thermal conductivity, high melting points and excellent oxidation resistance [152,153].…”

Zirconium-based alloys have served the nuclear industry for several decades due to their acceptable properties for nuclear cores of light water reactors (LWRs). However, severe accidents in LWRs have directed research and development of accident tolerant fuel (ATF) concepts that aim to improve nuclear fuel safety during normal operation, operational transients and possible accident scenarios. This review introduces the latest results in the development of protective coatings for ATF claddings based on Zr alloys, involving their behavior under normal and accident conditions in LWRs. Great attention has been paid to the protection and oxidation mechanisms of coated claddings, as well as to the mutual interdiffusion between coatings and zirconium alloys. An overview of recent developments in barrier coatings is introduced, and possible barrier layers and structure designs for suppressing mutual diffusion are proposed.

“…Based on the results of these experiments, we can confirm that zirconium sulfides played an important role in the formation of Zr 2 SB and the loss of sulfur is the main reason for the existence of impurity phases ZrB 2 and zirconium. As a rapid sintering method, SPS [26][27][28][29][30][31] can control the escape of sulfur and purify samples as much as possible, but the sintering of Zr 2 SB is still difficult. In our experiment, the best relative ratio of sulfur under these experimental conditions were 1.6.…”

In this paper, Zr2SB ceramics with high relative density (99.03%) and high purity of 82.95 wt% (containing 8.96 wt% ZrB2 and 8.09 wt% zirconium) were successfully synthesized from ZrH2, sublimated sulfur and boron powder by spark plasma sintering at 1300 ℃. The reaction mechanism, microstructures, physical properties and mechanical properties of Zr2SB ceramic were systematically studied. The results show that Zr2SB was obtained by the reaction of zirconium sulfide, zirconium and boron, and ZrB2 coexisted in the sample as a symbiotic impurity phase. The average grain size of Zr2SB was 12.46 μm in length and 5.12 μm in width, and the mean grain sizes of ZrB2 and zirconium impurities were about 300 nm. In terms of physical properties, the measured thermal expansion coefficient was 7.64 × 10-6 K-1 from room temperature to 1200 ℃, and the thermal capacity and thermal conductivity at room temperature were 0.39 J·g−1·K−1 and 12.01 W∙m−1∙K−1, respectively. The room temperature electrical conductivity of Zr2SB ceramic was measured to be 1.74 × 106 Ω−1∙m−1. In terms of mechanical properties, Vickers hardness was 9.86 ± 0.63 GPa under 200 N load, and the measured flexural strength, fracture toughness and compressive strength were 269 ± 12.7 MPa, 3.94 ± 0.63 MPa·m1/2, and 2166.74 ± 291.34 MPa, respectively.
