Abstract
The relationship between Vickers and Brinell hardness numbers of dental casting gold alloys was found to be linear; the addition of 19 to the Brinell number approximated the Vickers number fairly well. The coefficient of variation for the Brinell test was about 1 % less than that of the Vickers test. Effects of reading error, sample inhomogeneity, and other factors on the precision of the Vickers values were evaluated.Keywords
