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
Nickel Aluminum Bronze (NAB) alloys display characteristics like superior strength and excellent wear resistance. In this work, NAB was reinforced using various volume fractions of yttrium (YO) and/or carbon nanotube (CNT) particles prepared using the Powder Metallurgy (PM) method. General full factorial design was used in MiniTab19 software. The experimental results showed a significant influence of the YO and CNT particles on mechanical and physical properties. The optimal results were recorded for the sample having 6 vol.% of YO and 1.5 vol.% of CNT. This sample exhibited the highest effect on characteristics with hardness value of 288 Hv, porosity of 10.2%, surface roughness of 0.15 µm, average particle size of 37.55 µm, wear rate of 0.0000313 g/mm, and friction coefficient of 0.68. The results demonstrated that there is an improvement of 64% in microhardness in comparison with the base alloy. Porosity, surface roughness, wear rate, friction coefficient, and average grain size were reduced by 4%, 81%, 71%, 31%, and 24%, respectively.
