Alloys and metals are believed to play a fundamental role in the development of contemporary engineering and technology with properties that are different from their elementary ingredients. Because of their strength, ductility, and various types of conduction, metals are not only of great importance in applications ranging from construction to electronics, but they have also had limitations in being used as pure materials in their natural state because the alloys fill the meager mechanical properties of such pure metals.

Alloys are mixtures of at least two elements, one of which is a metal. Alloying improves upon the qualities of the base metal, and the result is sometimes materials that are stronger, lighter, or even more resistant to corrosion than their pure counterparts. For example, steel, which is an alloy of iron with carbon, has greater strength and toughness but this metal remains very much of practical application in construction and manufacturing.

Many of the notable inventions have been produced by advances in the development of alloys and find their way into other industries. Aluminum alloys are highly used in aerospace applications. The whole process of manufacturing these alloys is perfected to obtain satisfactory strength-to-weight ratios and corrosion resistance. Titanium-based alloys are widely applied in medicine due to its biocompatibility and high resistance capability to stresses. Their application is therefore found in the use of implants and surgical instruments.

Metallurgy is the study of metals and their properties and is important in understanding how different compositions and processing methods affect the performance of metals and alloys. Techniques, such as heat treatment, alloying, and casting, can drastically change the microstructure and, consequently, the properties of these materials.

Recent activities in metallurgy are dedicated toward developing high performance alloys tailored for specific applications, amongst others with respect to lightweight automotive application and aeronautical superalloy for high-temperature applications. This research focuses on additive manufacturing or 3D printing to create complex geometries and customized alloy composition.

The study of metals and alloys, therefore, becomes essential because it gives an insight into how they actually behave and perform in various areas of application. Constant improvements in metallurgy and materials science continuously lead to newer and advanced developments of alloys, which constantly enable new areas of innovation in science and technology within engineering, facilitating a manufacturing process that results in stronger, lighter, and more durable materials.
