Alloys are materials made from a combination of two or more metals or a metal and a non-metal. They are used in a wide range of applications due to their enhanced properties compared to pure metals, such as increased strength, hardness, and corrosion resistance. Alloys can also exhibit unique characteristics like shape memory or superconductivity. Research in alloys focuses on developing new compositions, improving processing techniques, and exploring new applications for these versatile materials. This field of study plays a crucial role in advancing technology and innovation in industries such as aerospace, automotive, and electronics.
