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
Laser surface melting (LSM) is a versatile technique used to modify surface properties without affecting the bulk characteristics of materials. This paper investigates the effects of LSM with pre-heating at different temperatures on the induced residual stresses, hardness, and surface topography of Ti6Al4V alloy. A finite element-based numerical model is developed to analyse the cooling rate during the process. Cooling rates decrease, and melt pool dimensions increase in LSM at elevated temperatures. This decreases the residual stresses and increases the microhardness. Experimental results reveal that higher pre-heating temperatures lead to up to 42% reduction in residual stress and up to 25% improvement in microhardness, with minimal effect on surface topography. This study highlights the efficacy of elevated temperature LSM to mitigate residual stresses and enhance surface hardness, which is promising for defence, aerospace, and automotive applications.
