Optical microscopy and SEM\/EDS were used to examine grain structure and local particle-containing regions, while XRD was used for qualitative phase assessment. The recorded mean grain sizes for 0, 0.3, 0.5, 0.7, 1, 2, and 3 wt.% SiC are 31.279, 29.004, 27.919, 23.579, 23.453, 21.797, and 17.539 \u03bcm, respectively. Tensile strength and Vickers hardness increased to their highest measured values at 2 wt.% SiC and then decreased at 3 wt.%. Elongation varied non-monotonically but also reached its highest measured value at 2 wt.% SiC. The 2 wt.% composite reached a tensile strength of 179.2 MPa, a hardness of 76.99 HV, and an elongation at break of 17.12%. The comparative XRD patterns are dominated by fcc Al. Open SiC and Si symbols denote reference positions only; weak SiC and Si reflections cannot be reliably distinguished under the present signal-to-noise level and mixed acquisition conditions. The XRD results therefore do not independently confirm a retained SiC phase or a quantitative phase fraction. Grain refinement and thermal-mismatch dislocations provide plausible strengthening mechanisms, whereas the modeled Orowan and load-transfer terms are small at the micron-scale particle size. The lower properties at 3 wt.% coincide with pore-like features in representative SEM fields, but the separate effects of porosity, clustering, and interface integrity remain unquantified.<\/jats:p>","DOI":"10.3390\/ma19194118","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T12:46:29Z","timestamp":1790599589000},"page":"4118","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of SiC Content on the Microstructure and Properties of 6082 Aluminum Matrix Composites"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5247-2902","authenticated-orcid":false,"given":"Wenzhan","family":"Huang","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, Taiyuan University of Science and Technology, Taiyuan 030024, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Yixuan","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Taiyuan University of Science and Technology, Taiyuan 030024, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"}]},{"given":"Zexin","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Taiyuan University of Science and Technology, Taiyuan 030024, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"}]},{"given":"Jingkai","family":"He","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Taiyuan University of Science and Technology, Taiyuan 030024, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"validation","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5643","DOI":"10.1016\/j.jmrt.2024.10.212","article-title":"A review on aluminum alloys produced by wire arc additive manufacturing (WAAM): Applications, benefits, challenges and future trends","volume":"33","year":"2024","journal-title":"J.
