Abstract
Small amounts of silicon added to steel act as a deoxidizer and lower the ductile-brittle transition temperature of the steel plate. Larger amounts, depending on the amounts of other deoxidizers already present, become an alloying addition and raise the transition temperature. Increasing aluminum contents up to 0.20 pet lowered the transition temperature at a rate depending on the amount of silicon and manganese present.
