Effect of calcium on grain boundary embrittlement of structural steel strengthened with carbonitrides

  • 31 Accesses

  • 1 Citations


Economically alloyed structural steels with carbonitride strengthening are widely used in the pipe and ship-building industries. These steels are liable to cold brittleness, one of whose causes is low-energy intergrain fracture due to intercrystal lite, internal adsorption (IIA). The authors investigate the effect of calcium on the cold brittleness of structural steels.
