Zr,Nb对Fe—B合金非晶形成能力的影响

EFFECT OF Zr AND Nb ELEMENTS ON GLASS FORMING ABILITY OF Fe-B ALLOY

根据获得高玻璃形成能力（GFA）非晶合金的多元化理论，研究了Zr，Nb对二元Fe—B非晶合金GFA的影响．结果表明，高B含量Fe—B非晶合金中加人适量Zr能够促进玻璃态转变．三元Fe—B—Zr非晶合金中加入少量Nb能够有效地提高其GFA．多元化是促进非晶合金玻璃态转变和提高其GFA的有效方法．

Effect of Zr and Nb elements on glass-forming ability (GFA) of Fe-B amorphous alloywas studied according to the empirical rules for the achievement of metallic glass with large GFA. Theaddition of Zr element into Fe-B alloys with 20% B results in the appearance of glass transition. The GFAof Fe-B-Zr alloys could be increased by addition of a small amount of Nb element. The multiplication tothe binary and ternary systems leads to the appearance of glass transition and increase of GFA.
