Chemical Properties of Engineering Materials

Being an Engineer it is important to have the knowledge of chemical properties of engineering materials. Because most the engineering materials come into contact with other materials and react chemically to each other. Due to this chemical reaction they may suffer from chemical deterioration. Some o

Physical Properties of Engineering Materials

To finalize the material for an engineering product or application, we should have the knowledge of physical properties of materials . The physical properties of a material are those which can be observed without any change of the identity of material. Some of these typical properties of a material

Free Electron Theory of Metals

The metals form a unique type of bonding known as metallic bonding and form the lattice structure. The uniqueness in such a type of bonding fashion lies in the fact that unlike ionic bonding and covalent bonding where the sharing of electrons is between two atoms and the electrons remain localized,

Antiferroelectricity

This is a physical property associated with antiferroelectric materials. Actually, these are materials having ions which can polarize without external field (spontaneous polarization). As a result, dipoles are ordered or arranged with alternating orientation. That is, adjacent lines will be in anti

pH Measurement

Partial pressures of hydrogen, carbon dioxide and oxygen are measured with blood gas analyzers. They determine the acid base balance in the body. When pH value goes below 7.35 it indicates respiratory acidosis and respiratory failure. It can be corrected using ventilator. At the same time when pH in

Electrical Impedance: What is it?

What is Electrical Impedance? In electrical engineering, electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. Impedance extends the concept of resistance to alternating current (AC) circuits. Impedance possesses both magnitude and phas

Magnetostriction: A Property of Magnetic Materials

Magnetostriction is defined as the property of some magnetic materials that causes them to change their shape or dimensions when they are magnetized by an external magnetic field . The change in size or length of a material due to magnetostriction depends on the strength and direction of the applied

Thermal Conductivity of Metals: How Heat Flows Through Different Materials

Thermal conductivity is a property that measures how well a material can transfer heat from one point to another without moving the material itself. It depends on factors such as the structure, composition, and temperature of the material. In this article, we will focus on the thermal conductivity o
