HUT041451 T The activator intended for use as a wire filler or in steel prodn. increases the strength of the alloy while retaining its plasticity. The compsn. is (% w/w): 16-36 Ca and/or Na, 13-30 Si, 2-28 V and/or Mo, 2-15 Nb and/or Pa, 2-15 Zr and/or Ce, 2-14 Ti, 1-15 Al and/or Ba, 0.1-3 B and/or Be, 1-5 C, 5-20 Fe and 1-10N. DEAB- DE3686585 G The activator intended for use as a wire filler or in steel prodn. increases the strength of the alloy while retaining its plasticity. The compsn. is (% w/w): 16-36 Ca and/or Na, 13-30 Si, 2-28 V and/or Mo, 2-15 Nb and/or Pa, 2-15 Zr and/or Ce, 2-14 Ti, 1-15 Al and/or Ba, 0.1-3 B and/or Be, 1-5 C, 5-20 Fe and 1-10N. EPAB- EP-294371 B A composition for addition to iron-based alloys to improve the strength thereof characterised in that, except for incidental elements and impurities, it consists of Ca and/or Na 16 to 30%; Si 13 to 30%; V and/or Mo 2 to 28%, Nb and/or Ta 2 to 25%; Zr and/or Ce 2 to 15%, Ti 2 to 14%; Al and/or Ba 1 to 15%; B and/or Be 0.1 to 3.0%; C 1 to 5%; Fe 5 to 20% and N 1 to 10%. (Dwg.0/0). USAB- US4906435 A An activator for addn. to steel melts to enhance the strength of the final prod. contains (percent) 0-30 Ca, 0-30 Na, 13-30 Si, 0-28 Mo, 0-25 Nb, 0-25 Ta, 0-25 Zr, 0-15 Ce, 2-14 Ti, 0-15 Ba, 0-15 Al, 0-3 B, 0-3 Be, 1-5 C, 5-20 Fe, 1-10 N, Ca+Na 16-30, V+Mo 2-28, Nb+Ta 2-25, Zr+Ce 2-15, Al+Ba 1-15 and B+Be 0.1-3.0. The additive is used at the rate of 5-17 kg per ton of steel melt.
