Mechanical Properties

Image
  The mechanical properties of a material are those properties that involve a   reaction to an applied load . The mechanical properties of metals determine the range of usefulness of a material and establish the service life that can be expected. Mechanical properties are also used to help classify and identify material. The most common properties considered are strength, ductility, hardness, impact resistance, and fracture toughness. Most structural materials are  anisotropic , which means that their material  properties vary with orientation . The variation in properties can be due to directionality in the microstructure (texture) from forming or cold working operation, the controlled alignment of fiber reinforcement and a variety of other causes. Mechanical properties are generally specific to product form such as sheet, plate, extrusion, casting, forging, and etc. Additionally, it is common to see mechanical property listed by the directional grain structure of t...

What is Mechanical Testing or Material Testing?

What is Mechanical Testing or Material Testing? Mechanical testing involves finding strength of the material or quality of material by application of load mechanically. There are different mechanical testing for materials. They are Tensile test, Bend Test, Impact Test, Macro Etch Test, Micro Analysis, Inter granular Corrosion test, Vickers Hardness Test, Brinell Hardness test and includes Spectro Chemical Analysis. Why is Mechanical Testing on Materials required? Mechanical tests mentioned above are essential for materials to conclude the quality of materials. The material grades are designed for some specific application, in order to withstand the loads and environment in the application. The materials grades should achieve the minimum specified property. These minimum required quality specifications are verified by manufacturer after pouring the material and manufacturer should provide a mill test report. What is MTC / What is Mill Test Report ? Mi...
