Superconductivity was discovered by Dutch Physicist Heike Kamerlingh Onnes in 1911 in Leiden. He was awarded the Nobel Prize in Physics in 1913 for his low-temperature research. Some materials when they are cooled, below certain temperature their resistivity get abolished means they exhibit the infinite conductivity.The property / phenomenon of infinite conductivity in materials is calledsuperconductivity.The temperature at which the metals change from normal conducting state to superconducting

To finalize the material for an engineering product / application, we should have the knowledge of magnetic properties of materials. The magnetic properties of a material are those which determine the ability of material to be suitable for a particular magnetic Application. Some of the typical magnetic properties of engineering materials are listed below- Permeability Retentivity or Magnetic Hysteresis Coercive force ReluctancePermeabilityIt is the property of magnetic material which indicates t

To finalize the material for an engineering product / application, we should have the knowledge of Electrical properties of materials. The Electrical properties of a material are those which determine ability of material to be suitable for a particular Electrical Engineering Application. Some of the typical Electrical properties of engineering materials are listed below- Resistivity Conductivity Temperature coefficient of Resistance Permittivity ThermoelectricityResistivityIt the property of mat

To finalize the material for an engineering product or application, is it important to understand the mechanical properties of the material. The mechanical properties of a material are those which affect the mechanical strength and ability of a material to be molded in suitable shape. Some of the typical mechanical properties of a material include: Strength Toughness Hardness Hardenability Brittleness Malleability Ductility Creep and Slip Resilience FatigueStrengthIt is the property of a materia

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 of the chemical properties of engineering materials are listed below – Chemical composition Atomic bonding Corrosion resistance Acidity or AlkalinityChemical CompositionThe chemical composition of engi

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 are listed below- Density Specific gravity State Change temperatures Coefficients of thermal expansion Specific Heat Latent heat Fluidity Weld ability Elasticity Plasticity Porosity Thermal conductivit
