@article{et al._2020, title={Effect of modification on microstructure wear resistance and mechanical properties of Al-12.4%Si alloy}, volume={29}, url={http://sersc.org/journals/index.php/IJAST/article/view/5017}, abstractNote={<p><span class="fontstyle0">This work verifies the effect of adding different weight percentages of alloying elements boron and<br>antimony 1,2 and 3 Wt% to Al-12.4% Si alloy by stir casting process on the wear rate, microstructure,<br>and properties after the mechanical test. A microstructure was an inspection by optical microscopy<br>of alloy before and after adding the additional elements. The examination represents that the change<br>occurs on the size and morphology of α-Al, also refining the silicon in the eutectic phase. The results<br>of the mechanical test showed that the hardness, yield strength, and tensile strength increased when<br>the Wt% of alloying elements additions increasing, but the elongation decreases when we compared<br>with the Al-12.4%Si alloy. The wear rate determined by the pin-on-disk device before and after<br>alloying elements adding. Also, we observed that the wear rate decreased when increasing the Wt% of<br>boron at different applied loads (5, 10, and15N) at a constant sliding speed (2.8) m/sec, and also at<br>fixed applied load (15 N) with variance sliding velocity such as (1.4,2.8, and4.2M/sec).</span> </p&gt;}, number={2}, journal={International Journal of Advanced Science and Technology}, author={et al., Dr. Israa}, year={2020}, month={Jan.}, pages={3756 -} }
