Therefore, the main goal of this paper is to design and develop verification standards for Brinell (HB) and Rockwell (HRC) scales from low alloy carbon steels subjected to different types of heat treatment. In order to a...
Testadores de dureza Vickers utiliza o teste de dureza que foi desenvolvido em 1924 por Vickers Ltd como uma alternativa ao método Brinell.
In hardness measure system, Brinell e Vickers, the process to obtain the diameter and e diagonal of the identation, is liable to errors, since when made by experienced operators. This happens because the boundary lines are not sharp and by the fact that the human vision needs to training ...
