The methods of optical and scanning electron microscopy and x-ray spectrum microanalysis are used to study and to compare the special features of formation of metastable trialuminides under rapid crystallization of superheated melts of the Al – Hf – Sc and Al – Hf – Ti systems. Heating of such melts by over 100°C above the liquidus temperature yields Al n (Hf 1– x S c x ) and Al n (Hf 1– x Ti x ) aluminides with a cubic lattice of structural type L1 2 .

在 Al – Hf – Sc (Ti) 系统的合金中形成亚稳态铝化物

使用光学和扫描电子显微镜以及 X 射线光谱微量分析的方法研究和比较在 Al-Hf-Sc 和 Al-Hf-Ti 系统过热熔体快速结晶下亚稳态三铝化物形成的特殊特征。将此类熔体加热到高于液相线温度 100°C 以上，会产生具有 L1 2 结构类型的立方晶格的 Al n (Hf 1– x S cx ) 和 Al n (Hf 1– x Ti x ) 铝化物。
