The multidisciplinary area of materials science focuses on the design and development of novel solid materials. The topic is also known as materials science and engineering, which focuses on the engineering elements of constructing usable objects, and materials physics, which stresses the application of physics to explain material characteristics. In the Age of Enlightenment, academics started to use analytical reasoning from chemistry, physics, and engineering to comprehend old phenomenological data in metallurgy and mineralogy. The field of materials science involves physics, chemistry, and engineering. Therefore, academic institutions traditionally regarded the area as a subfield of these connected disciplines. In the 1940s, materials science became more generally acknowledged as a separate branch of science and engineering, and the world’s leading technical institutions established schools devoted to its study.
In addition, Failure analysis, which investigates the failure of materials, objects, structures, or components that result in physical injury or property damage due to their inability to perform as intended, is likewise heavily dependent on materials science. For example, understanding the causes of a number of aviation accidents and occurrences requires such investigations.

Core subject of Material science
Materials Science is an interdisciplinary field of study that explores the fundamental principles governing the behavior of materials at the atomic and molecular levels. It seeks to understand the relationship between the properties of materials, their microstructures, and their synthesis and processing. Materials Science encompasses a broad range of subjects, including physics, chemistry, engineering, and biology, and has wide-ranging applications in industry, medicine, energy, and electronics.
The field of Materials Science is concerned with the investigation of materials, their properties, and how these properties arise from their underlying structure. Materials can be classified into several categories, including metals, ceramics, polymers, and composites. Metals are typically characterized by high strength, ductility, and conductivity. Ceramics, on the other hand, are generally brittle but have excellent resistance to high temperatures and wear. Polymers are known for their elasticity, flexibility, and low cost, while composites are formed by combining two or more different materials to create a new material with enhanced properties.
The study of materials begins with the understanding of their basic structure at the atomic and molecular levels. The behavior of materials is determined by their electronic structure, which describes how the electrons are arranged in the atoms that make up the material. The electronic structure of a material is affected by the arrangement of the atoms and the interactions between them.
One of the primary methods used to study materials is through microscopy, which allows scientists to observe the structure of materials at the atomic and molecular levels. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are commonly used techniques to visualize the structure of materials.
Another key aspect of Materials Science is the study of materials processing, which involves the creation of new materials and the modification of existing ones. Materials can be synthesized through a variety of techniques, including casting, extrusion, forging, and sintering. The choice of synthesis technique depends on the properties desired in the final product.
In addition to synthesis, materials processing also includes surface modification, which involves changing the surface of a material to achieve specific properties. This can be accomplished through chemical treatments, such as coating with a thin film, or by mechanical means, such as polishing or grinding.
Materials Science also involves the study of properties and how they relate to the microstructure of a material. Mechanical properties, such as strength and toughness, are of particular interest in Materials Science. Other important properties include electrical conductivity, thermal conductivity, and optical properties.
The properties of materials are often dependent on the microstructure of the material, which includes features such as grain size, composition, and defects. The microstructure of a material can be manipulated through materials processing techniques to achieve desired properties.
The study of Materials Science has numerous applications in a wide range of fields. For example, in the field of medicine, materials are used for the development of medical devices and implants.
