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 stress corrosion cracking (SCC) behaviour of nickel-based weld metal Alloy 182 was studied in simulated light water reactor environments with or without zinc (Zn) addition. Accelerated SCC initiation tests with flat tapered tensile specimens, as well as SCC initiation and short crack growth tests with compact tension specimens revealed that Zn injection is able to effectively mitigate SCC. Even the lowest tested Zn concentration of 15 ppb seems to be enough to achieve a significant mitigation effect on SCC initiation and short crack growth. This beneficial effect may be related to the modified surface oxide film by Zn incorporation.
