Limitations of Hardness Test 1) Hardness value alone cannot reflect the mechanical properties of different materials. For different materials, if their tensile strength (σb), yield strength (σs, or 00.2), elongation (ε), cross-sectional shrinkage (ψ) and impact toughness (ak) or impact energy (Ak) ... Read More

Advantages of Hardness Test in Application 1) When testing hardness, the stress state of its loading mode is the softest (a>2), that is, the maximum shear stress is much greater than the maximum normal stress. Any metal material will undergo plastic deformation under this stress state, and the ... Read More
