Metric Options: CountsSelecting 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
Alumina–niobium carbide (Al 2 O 3 –NbC and Al 2 O 3 –Nb 2 C) composites were synthesized by incorporating aluminothermic reduction of Nb 2 O 5 into a self-propagating combustion process. Starting materials of this study included Nb 2 O 5, Al, Al 4 C 3 and carbon powders. Experimental evidence indicated that combustion temperature and flame-front velocity decreased with increasing elemental carbon in the reactant mixture. The use of Al 4 C 3 as the source of carbon was demonstrated to prevent carbothermic reduction of Nb 2 O 5. As a result, the combustion exothermicity was increased and phase transformation and product densification were improved. According to the composition analysis, the carbon-free samples composed of Nb 2 O 5 :Al:Al 4 C 3 = 3:2:2 and 3:6:1 successfully produced NbC and Nb 2 C–Al 2 O 3 composites, respectively, with very few minor phases.
