Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The refractory high-entropy ceramics, TiZrHfNbTaB (x = 0, 0.1, 1, 10), which vary from high-entropy alloys to high-entropy ceramics depending on the B-content, were fabricated using the arc-melting method. TiZrHfNbTa (x = 0), TiZrHfNbTaB (x = 0–1), and (TiZrHfNbTa)B (x = 10) showed BCC, BCC with MB (M = Ti, Zr, Hf, Nb, Ta), and MB structures, respectively. The Vickers hardness and Young’s modulus of these materials increased with an increasing B-content because these ceramic properties are superior to those of metals. The weight gain during oxidation, measured using thermogravimetric analysis, revealed that the highest and lowest weight gains were observed for TiZrHfNbTaB and (TiZrHfNbTa)B, respectively. Their weight gain depends on their crystal structures rather than their B-contents.
