Iron and Steel's microconstituents are Austenite, Ferrite, Cementide, Pearlite, Bainite, Martenite, Troostite, Sorbite, and Ledeburite. Austenite (γ-iron):  It is a solid solution of ferrite iron carbide in gamma iron, which is formed when steel contains carbon u…

There are many theories of fatigue; I have written briefly about three of them: the Orowan theory, the fatigue limit theory, and Wood’s theory. 1. Orowan Theory: Orowan theory considers the metal to contain small, weak regions. Slip occurs readily along these regio…

Mechanical properties help us measure how materials behave under a load. The mechanical properties of materials are mentioned below. Elastic Material: Elastic stress is a material that regains its original size and shape after removing stress. Plastic material: Plas…

Superalloys , also known as high-performance alloys, are a group of materials designed to operate in extreme conditions, such as high temperatures, high-stress environments and chemically challenging atmospheres. They are commonly used in applications requiring strengt…

Often, materials are subject to an external force when they are used. Mechanical engineers calculate those forces, and material scientists determine how materials deform or break as a function of force, time, temperature, and other conditions. Materials scientists lear…
