Abstract
A method for predicting the ultimate tensile strength (S u ) of a material from Brinell-type hardness tests is described for several metals including steel, aluminum, and copper alloys. The prediction of S u is based on a consistent relationship between S u and a material’s hardness coefficient, K d . A simple experimental procedure for determining K d from indentation-hardness test data is presented. The relationship between S u and K d is found to be 1/3 for all cubic metals. Comparisons between predicted and experimentally determined values of S u are made for each of the materials studied, and sources of error between the two S u values are discussed.
