FRACTURE TOUGHNESS OF WELDMENTS IN HIGH-STRENGTH STEELS

The fracture toughness of weldments increases when they are alloyed with up to 4% Ni and Cr, up to 2% Mn, and up to 1% Cu, Co, and W. Alloying with molybdenum lowers the fracture toughness. The difference in the effects of alloying elements on the fracture toughness of the weld seam and the base metal is due to their effects on the austenite grain size and the evenness of carbon distribution. Grain refining and large microheterogeneities increase the fracture toughness.
