網頁Thus the Brinell test, unlike the Rockwell test, may not qualify as a nondestructive test for measuring hardness of materials. Further, the hardness range that can be measured utilizing Brinell hardness test is much narrower than in the case of the Rockwell or Vickers hardness tests, since the latter tests utilize diamond indenters. 布氏硬度試驗（Brinell scale）是壓入硬度試驗之一種，其測量值用HB或BHN表示。 該試驗最初由瑞典工程師 Johan August Brinell（1849年-1925年）於1900年提出。布氏硬度是第一個被廣泛用於工程學及冶金學的標準化硬度試驗。此試驗方法因壓痕較大和對待測材料損傷明顯，應用受到一定限制。 查看更多內容 布氏硬度試驗一般採用直徑10毫米的球形鋼壓頭，用一定的負荷（試驗力）壓入被測材料表面。常見的試驗力可高達3,000千克力（29千牛頓）；對於軟的材料則可用較小的負荷。如果試驗材料很硬，則以碳化鎢球壓頭代替鋼壓 … 查看更多內容 • 國際標準： ISO 6506-1:2005 Ed. 2 Brinell hardness test Part 1: Test method ISO 6506-2:2005 Ed. 2 Brinell … 查看更多內容 • 硬度試驗 • 維氏硬度試驗 • 洛氏硬度試驗 • 努氏硬度試驗 查看更多內容

網頁The Brinell hardness test is commonly used to determine the hardness of materials like metals and alloys. The test is achieved by applying a known load to the surface of the tested material through a hardened steel ball of known diameter. 網頁The Brinell hardness test is an optical method where the indentation size left by the indenter is measured. Contrary to the similar optical Vickers method, which involves a pyramid-shaped indenter being pressed into the specimen, the Brinell testing method uses a spherical indenter. 網頁2011年7月26日 · The first widely accepted and standardized indentation-hardness test was proposed by J. A. Brinell in 1900. Brinell’s interest in materials science grew during his involvement in a several Swedish iron companies and his desire to have a consistent and fast means of determining material hardness. psssf offices dar es salaam
