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
Equiatomic TiZr(Hf, Ta, Nb) medium entropy alloys (MEAs) were developed to achieve higher corrosion resistance than pure Ti. Nb and Ta alloying can greatly improve the corrosion resistance of Ti-50Zr (at%) alloys by reducing point defects in passive films. The oxide thickness for elements in passive films on TiZr(Hf, Ta, Nb) alloys increase significantly, following Hf > Zr > Ti > Nb > Ta, which was determined by the ability of elements to form oxides. Serious ploughing and delamination wear result in a higher tribocorrosion rate for TiZrNb alloy. The wear mechanisms for the three MEAs was discussed.
