Eye and Binocular: The Man-MachineThe hardness of metals can be defined as resistance to plastic deformation and test methods are based on forcing an indenter into the surface under a known load. Two such tests are the Brinell test and Vickers diamond test. In each case the hardness number is given by indenting force divided by the surface area of indentation.作者: 有斑點(diǎn) 時(shí)間: 2025-3-23 01:09

Single phase fields are always separated by a two-phase field and three phases can only coexist at a unique point, for example, a eutectic point.作者: CHAFE 時(shí)間: 2025-3-25 23:40 作者: FLIP 時(shí)間: 2025-3-26 03:06
