Heat treatment of metal is a term used to describe an operation or a series of operations which involves heating and cooling of a metal or an alloy when it is in the solid state for obtaining some desirable properties (without changing the chemical composition ). The main objective of Heat Treatment of Steel 1. Enhancing the hardness of the steel. 2. Stress reliving from the metal after hot

Bernoulli's Equation states that - For an incompressible liquid (density constant) which is flowing in a continuous stream; the total energy remains the same for all the particles, when the particle is moving from one point to another point. Mathematical expression of Bernoulli's equation: P1/w + (v2 )1/2g + z1 = P2/w +( v2)2 /2g + z1 = constant Here P1 , P2 = Pressure at points 1

Stress-strain are very important terms of solid mechanics. Strength of materials is a branch of engineering which deals with the material's properties to resist its failure. This topic also discusses about the behavior of materials under different level of forces. What is stress and strain In this topic we will discuss the definition of stress and strain, their formula as well as relationship

A design engineer must have a good concept about the mechanical properties of materials. Different manufacturing processes and heat treatment can change the properties of materials. A good design engineer should have a good knowledge about these properties. Engineering materials are divided in the following divisions - 1. Metal and Metal Alloys . Example : Iron, Copper, Nickel etc. 2. Non-

Mild steel is the most commonly used steel. It is used in the industries as well in the different everyday objects we use. Even the pans and spoons of the kitchen are sometimes made of mild steel. The main target of this article is to discuss about different mild steel properties. The mild steel is very important in the manufacturing of metal items. Almost 90% steel products of the world is made

The energy from the sun reaching the earth per day ranges from about 600 Btu (British Thermal Unit) / square feet for Northern Europe to about 2000 Btu/square feet for arid regions near the equator. More energy from sun strikes the earth in one hour than all energy consumed on the planet in a year! A summer day’s sun at noon provides a square, meter of land with a power input almost a kilowatt.
