Heat Treatment Process-Annealing, Normalizing, Hardening, Tempering, Nitriding, Cyaniding Process, PDF

Heat Treatment: In very simple words I am going to explain the heat treatment process consists of a succession of heating and cooling cycles applied to a metal or alloy in order to obtain the desired properties, such as hardness, ductility, tensile strength, toughness, grain size, etc. Heat treatment involves heating of metal in the […]

Properties of Metals: Mechanical, Electrical, Thermal, Magnetic, Chemical Properties [PDF]

[dropcap]H[/dropcap]ello Readers, today we will discuss Properties of Metals in brief, before dive into the topic let me give you an idea about metal. The metals are defined as the element substances found in nature. They are available chemically combined with other elements. Metals are extracted from there ores. Now let's dive into the properties of […]

Stress and Strain-Definition, Curve or Diagram, Formula, PDF

Stress and Strain Definition: In engineering, stress has been defined is: when an external force applied to the object(made of an elastic material), they produce a change in shape and size of the object. Stress is defined as, the deformation force per unit area of the body or material. Stress is the internal force(per unit area) […]

Surface Texture or Finishing-Definition, Surface Roughness Methods, PDF

Surface Texture or Finishing Definition: Surface finish, Also known as surface texture or surface topography, is the nature of the surface, as defined by three characteristics of lay, surface roughness, and waviness. The surface texture is one of the important factors that control friction. Each manufacturing process, (such as the many kinds of machining) produces […]
