稳定准晶相的形成与该合金组元的尺寸、电子因素差异等密切相关.通常,人们将这些尺寸、电子因素或它们的组合用于研究合金的形成能力及稳定性.将组元尺寸因素与原子参数方程用于第五、六过渡族金属基(Y,Zr,Nb,Mo,Ru,Rh,Pd,La,Hf,Ta,W,Re,Os,Ir,Pt)准晶合金的形成能力研究,发现准晶形成区与非形成区可以用一椭圆曲线(x?m)2/c2+(y?n)2/d2=1加以区分,准确率分别达到97.4%和95.5%.同时发现,椭圆曲线的参数m,n,c和d与基体元素的原子参数成对应关系.
The formation of a stable quasicrystalline phase is closely related to the size of the alloy element, the difference of electronic factors, etc. Usually, these sizes, electronic factors, or a combination thereof are used to study the formation ability and stability of the alloy.According to the size factor And atomic parameter equations for the formation of quasicrystalline alloys of the fifth and sixth transition metal groups (Y, Zr, Nb, Mo, Ru, Rh, Pd, La, Hf, Ta, W, Re, Os, Ir, Pt) It is found that the quasi-crystalline region and the non-formation region can be distinguished by an elliptic curve (x? M) 2 / c2 + (y? N) 2 / d2 = 1 with the accuracy reaching 97.4% and 95.5% respectively. The parameters m, n, c and d of the elliptic curve correspond to the atomic parameters of the matrix element.
