针对铝合金直接氮化生长AlN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AlN晶体的生长特征,研究了铝合金直接氮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 AlN crystal in directed nitridation of molten aluminium alloys was Investigated. The growing characters of AlN 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.
