Bruscato factor in temper embrittlement of welds

Abstract

Published experimental data on the tendency for 2.25Cr–1Mo to undergo impurity induced temper embrittlement have been analysed quantitatively. The results indicate strong effects owing to 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.
