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
Hypereutectic Al–Si alloy (A392) was treated with ultrasonic vibration (UV) induced to the melt through a cylindrical resin–bonded sand mold. This work aims at studying the influence of UV at the different pouring temperatures of A392 alloy during solidification process on the microstructures and mechanical properties. The microstructures of as-cast samples were examined by using optical microscopy (OM) and scanning electron microscopy (SEM). The mechanical properties were investigated by tensile and hardness tests. The results showed clearly that with applied UV at optimum pouring temperature (640 oC), nearly fine uniform and polyhedral shape of the primary Si were obtained. Improvement of tensile properties and hardness of the investigated alloy modified with UV is related to the modification and refinement of primary Si particles. The fracture surfaces of prepared alloy without and with UV were also investigated.
