The Bruscato Factor in the Temper Embrittlement of Welds

Abstract

Published experimental data on the tendency for 2.25Cr1Mo steel welds to undergo impurity-induced temper embrittlement have been analysed quantitatively. The results indicate strong effects due to the phosphorus, silicon, manganese and molybdenum concentrations, but the influence of tin, antimony and arsenic cannot be perceived because of the overwhelming effects of the other elements. A computer model for the calculations is obtainable freely over the world-wide-web.
