针对铝合金直接氮化生长ＡＩＮ过程中的晶体生长过程进行分析，通过Ｘ－ｒａｙ衍射和ＳＥＭ观察，获得了不同生长阶段ＡＩＮ晶体的生长特征，研究了铝合金直接氨化生长氮化铝的反应机制．提出了一种气－液－固－固）晶体生长机制，简称ＶＬＳＳ机制，并着重对ＶＬＳＳ机制的实现条件、实现过程以及与传统的ＶＬＳ晶体生长机制的相同点和差异进行了讨论．
The growing process of AIN crystal in directed nitridation of molten aluminium alloys was investigated. The growing characters of AIN crystals were obtained through XRD and SEM. A new mechanism of vapour-liquid-solid-solid (VLSS) was proposed, and its similarity and difference from the traditional vapour-liquid-solid (VLS) mechanism were discussed. The emphasis was placed on the prerequisites and realization process of VLSS mechanism
