The authors investigate methods of elimination of brittle intergranular fracture in steels containing phosphorus in quantities allowed by specifications, i.e., predisposed to intergranular brittle fracture. The methods discussed include: alloying of steels with molybdenum or tungsten in a quantity not sufficient for formation of special carbides; the formation of a structure of pre-precipitation of special carbides; and the use of those steels in which the content of carbide-forming elements with a high beta-MP significantly exceeds the quantity of carbon in them. The authors conclude that there is no universal method of complete elimination of temper brittleness of alloy steels containing phosphorus. However, in each specific case real possibilities may be found for suppression of temper brittleness of steels.
