Bruscato factor in temper embrittlement of welds

Published experimental data on the tendency for 2.25 Cr-1 Mo to undergo imp urity induced temper embrittlement have been analysed quantitatively. The r esults indicate strong effects owing to phosphorus, silicon, mangenese, and molybdenum concentrations, but the influence of tin, antimony, and arsenic cannot be perceived because of the overwhelming effects of the other eleme nts. A computer model for the calculations is obtainable freely over the Wo rld Wide Web.
