Effect of rare-earth La on microstructure and mechanical properties of Al7Si4CuMg alloys prepared by squeeze casting

The effects of rare-earth lanthanum (La) on the microstructure and tensile properties of Al7Si4CuMg alloys prepared by squeeze casting were studied by microscopy technologies, thermal analysis and tensile tests. The results demonstrate that La can refine α-Al grains, modify eutectic Si and improve t...
