New iron-base eutectic powder alloys have been developed (Fe−Mn−C−B−Si−Ni−Al−Sc, Fe−Mn−C−B−Si−Cr−Al−Sc, Fe−Mn−C−B−Si−Ni−Cr−Al−Sc) for wear-resistant coatings. The thermodynamic affinity for oxygen has been

1. The cold-resistance of the 14G2 steel increases markedly after its microalloying by an optimum amount of titanium and boron (0.026% Ti and 0.0014% B). This is associated with an improvement of the microstructure, a reduction of the volume content
