    What Is Material Hardness?Types of HardnessDifferent Hardness UnitsMeasuring HardnessHardness is the measure of a material’s resistance to localised permanent deformation. Permanent deformation is also called plastic deformation. While elastic deformation means that a material changes its shape only during the application of force, a resulting plastic deformation means that the material will not return to its original shape. Some materials are naturally hard. For example, tungsten is an incredibly hard metal that find在fractory上查看更多信息预计阅读时间:8 分钟
