Properties of binary and ternary iron based alloys doped by different additions were investigated. It was shown for binary alloys containing chromium, molybdenum and tungsten were that results of doping by 0.8% molybdenum and tungsten are similar to those for the sample doped by 9%chromium. Ternary alloys containing chromium and less amounts of molybdenum, tungsten and vanadium were investigated as well. Two types of defects were observed: divacancies and cluster-like defects. It was shown that the electron density in ternary alloys is similar to that in binary alloys containing 0.8% molybdenum.

ABSTRACTHigh-manganese ferrous-based alloys containing 10–20 at. % Mn have been investigated as prospective iron-based structural amorphous metals with magnetic transition temperatures far below the ambient temperature. Many of these alloys are found to have a high reduced glass transition temperature of 0.6–0.63 and large supercooled liquid region of 40–90 °C. Rod-shaped amorphous samples with diameters reaching 4 mm are obtained by employing simple injection casting. The search for good glass-forming alloys has been guided by an atomistic approach coupled with the realization of low-lying liquidus temperatures via proper alloying. The tensile yield strengths and Vickers hardness of the new amorphous metals far exceed those known in high-strength steel alloys, and the elastic moduli are comparable to those reported for super-austenitic steels. The present high-manganese amorphous Fe-alloys also show promise as very good corrosion-resistant materials.
