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
In the present study, a uniform distribution of nanosized TiB particles in the metal matrix was achieved by powder metallurgy using the composite powders with pre-embedded particles. The composite powders were consolidated into compacts via spark plasma sintering without additional treatment such as mechanical milling or mixing. The concentrated shear stress around the uniformly distributed TiB particles with size similar to the width of the elongated grains during hot extrusion leads into grain fragmentation and refinement. The T4-treated TiB/2024 composites had a better combination of yield strength of 385 MPa, ultimate tensile strength of 568 MPa and uniform elongation of 14.6% compared to the Al-Cu-Mg alloys and Al-Cu-Mg based composites in the published work. The longer uniform elongation of the composites in the present work was analyzed in respects of dislocation accumulation rate k and dislocation recovery rate k.
