Lot of development has taken place in the field of materials. New materials are being developed and it
has become possible to change the properties of materials to suit the requirements.
Mechanical Engineering are required to make use of different materials for various applications. For this purpose, it is necessary to teach them basics of metal structure, properties, usage and testing of
various ferrous and non ferrous materials and various heat treatment processes. This subject aims at
developing knowledge about the characteristics, testing and usage of various types of materials used in
Mechanical Engineering industry.
Insulating Materials: Insulating materials, also known as insulation or insulators, are substances or materials that resist the flow of electric current, heat, sound, or other forms of energy. They are used to prevent the transfer of energy between objects or areas, thereby reducing the loss or transfer of heat, electricity, or sound. These materials are … Read more
Plastics: Plastic is a synthetic material made from polymers, which are long chains of molecules derived from petroleum or natural gas. It is characterized by its malleability, durability, lightweight nature, and versatility in various applications, these polymers can be molded and shaped into various forms due to their malleability when heated. Importance of Plastic: Properties … Read more
Non-ferrous materials: Non-ferrous materials refer to metals and alloys that do not contain iron as their primary elemental component. These materials have unique properties and applications compared to ferrous metals (which contain iron). Some common non-ferrous materials include aluminum, copper, lead, zinc, nickel, titanium, and alloys like brass and bronze. The properties of non-ferrous materials … Read more
Definition of Steel: Steel is an alloy of iron and carbon, typically containing less than 2% carbon by weight, along with other elements such as manganese, chromium, nickel, or molybdenum. It is characterized by its strength, ductility, and versatility, making it a widely used material in construction, manufacturing, and various industries. These Steels are called … Read more
CAST IRON: Cast iron refers to the family of Ferrous metal which are used in the cast form. Cast iron consists of carbon more than 2%. It is refined from Pig iron. It is known for its high strength, wear resistance, and excellent castability, making it suitable for a wide range of applications in various … Read more
Properties of materials: Different engineering application require different type of materials. It is essential that the design and production engineers must be familiar with the properties of materials. In order to design and manufacture component and structures and to avoid failure during use knowledge of the properties of material is desired. Metals and alloys have … Read more
Engineering materials: Engineering materials refer to substances or compounds that are specifically designed and used for various engineering applications. These materials are selected based on their properties, such as strength, durability, conductivity, and thermal resistance, to meet the requirements of a particular engineering project. Engineering materials can be broadly categorized into metals, non-metals, polymers, ceramics, … Read more
