Hardness of Testing

(Hardness) is The ability of the material to receive the load of identor to occur plastic deformation. Deformation Plastis (a state of a material when the material is given the style of the microstructure of the material could not go back to the original form of the material means can not return to its original shape). One of the mechanical properties (mechanical properties) of a material. Hardness of a material must be known in particular for the material in its use will mangalami friction (frictional force) and plastic deformation. Depth or the result of suppression is a function of the hardness, the more soft a material more widely and more deeply as a result of the emphasis, and the lower the hardness value.
