从技术和经济的角度来看，原位处理比传统处理具有显著的优势。Al-TiO 2是最近受到一些关注的有趣系统之一。本文采用热分析、XRD和显微结构表征等方法研究了Al-TiO_2体系中Al_3 Ti和Al_2 O_3的形成机理。据发现，在原位处理包括三个中间步骤。此外，TiO和γ-Al 2 O3是在反应过程中形成的过渡相。(C)2000爱思唯尔科技有限公司版权所有。
In-situ processing offers significant advantages over conventional processing from both technical and economic standpoints. Al-TiO2 is one of the interesting systems that has recently been receiving some attention. In this paper, the formation mechanism of Al3Ti and Al2O3 from an Al-TiO2 system is investigated by using thermal analysis, XRD and microstructural characterisation. It is found that the in-situ processing involves three intermediate steps. In addition, TiO and gamma-Al2O3 are transitional phases, which form during the reactive process.
