WebThe Brinell Hardness Number is used to convey the hardness of the given material. This Brinell Hardness Number is termed as the BHN and it is the function of the force applied divided by the surface area of the indentation made by the ball on the given material. The units of the BHN are kgf/mm 2. If the BHN number is multiplied by the ... WebKeménység[ bevezető szerkesztése] Keménység.

It is named after the Brinell scale of hardness, in which a small ball is pushed against a hard surface at a preset level of force, and the depth and diameter of the mark indicates the Brinell hardness of the surface. Brinelling is permanent plastic deformation of a surface, and usually occurs while two surfaces in contact are stationary (such as rolling elements and the raceway of a bearings) and the material yield stren… if i.use medicaid diversity visaWeb布氏硬度试验（Brinell scale）是压入硬度试验之一种，其测量值用HB或BHN表示。. 该试验最初由瑞典 工程师 Johan August Brinell（1849年-1925年）于1900年提出。 布氏硬度是第一个被广泛用于工程学及冶金学的标准化硬度试验。 此试验方法因压痕较大和对待测材料损伤明显，应用受到一定限制。 is sports gambling legal in paBrinell hardness is sometimes quoted in megapascals; the Brinell hardness number is multiplied by the acceleration due to gravity, 9.80665 m/s 2, to convert it to megapascals. The BHN can be converted into the ultimate tensile strength (UTS), although the relationship is dependent on the … See more The Brinell scale /brəˈnɛl/ characterizes the indentation hardness of materials through the scale of penetration of an indenter, loaded on a material test-piece. It is one of several definitions of hardness in materials science See more Proposed by Swedish engineer Johan August Brinell in 1900, it was the first widely used and standardised hardness test in engineering and metallurgy. The large size of indentation and possible damage to test-piece limits its usefulness. However, it also … See more When quoting a Brinell hardness number (BHN or more commonly HB), the conditions of the test used to obtain the number must be specified.
