This work offers a deeper understanding of the nature of material hardness at the atomic level, and provides a practical guide in the search for new superhard materials.doi:10.1007/s11434-008-0550-8KeYanLiDongFengXueCNKI科学通报(英文版)KeYan Li,DongFeng Xue.Hardness of materials: studies at ...
2.4 Hardness in L12 structures 2.4.1 What is hardness Hardness is the resistance of material to indentation or other penetration deformation. The most common hardness measurements are Brinnel, Rockwell, Vickers, or Knoop. A constant compression load is applied to a chosen indenter who penetrates th...

High hardness material and process for its manufacture. Such a material essentially corresponds to the formula Bx Cy Nz in which x, y and z are greater than or equal to 1 and is in tetrahedral form (cf. figure), the preferred material being of formula BCN. This material is produced by ...
Fig. 5.1illustrates a flowchart of the quantitative interlink wear estimation method previously proposed by the authors [21]. In this method, physical properties such as wear coefficient andVickershardness need to be obtained by material test (e.g., pin-on-diskwear and Vickershardness test) for...

Knoop hardness (HK) test (ISO 22394) is also used when the anisotropy of material is of interest, as it is the case in WC crystals (Exner, 1979; French & Thomas, 1965). A wide variety of load weights of 100, 50, 30, 20, 15, 10, and 1 kg are used for measuring the HV, ...

For example, both hardness and tensile tests measure the resistance of a material to plastic flow; results of these tests exhibit close parallels. A hardness test is often preferred because it is relatively non-destructive in nature. The choice of the hardness test depends on the material being...
