Paragraph starter
The study by Sinha (2012) highlights metal foams as a significant advancement in metallurgy, demonstrating that controlled porosity can yield unique material properties such as ultra-low density, high stiffness, and excellent energy absorption. This challenges the conventional view that defects reduce material performance and opens up new design possibilities for applications where conventional solid metals are insufficient.
