    摘要:

    利用形核理論,對人塊非晶合金的形成條件、控制因素、合金成分設(shè)計思路、制備原理與技術(shù)等進(jìn)行了分忻與討論。非均勻形核的避免和均勻形核的抑制是大塊非晶合金成功制備的充分必要條件,前者要通過外部熔煉條件的有效控制來實現(xiàn),包括:熔煉提純、合理的冷卻介質(zhì)和惰性氣氛保護(hù)等:后者要通過合理的成分設(shè)計來實現(xiàn),包括:多組元、高原子尺寸比、人負(fù)混合熱、低熔點組元或低熔點共晶。

    Abstract:

    Forming conditions, control factors, alloy design methods, manufacturing principle and technology of bulk amorphous alloys are analyzed and discussed using nucleation theory. The complete and necessary conditions of bulk amorphous alloy formation are preventing inhomogeneous nucleation and restraining homogeneous nucleation. The former can be realized by controlling effectively exterior melting conditions including purification, optimum cooling medium and inert atmosphere protection, et al. The latter can be achieved by the reasonable alloy design that involve multi-components, high ratio of atom radius, large negative blending heat, composition with low melting point or low eutectic point.
