中文摘要：

高纯净的 Ti2AlN 陶器被热压在 1300 ° C 准备(HP ) Ti/Al/TiN，在 stoichiometric 的粉末分配。sintered 产品用 X 光检查衍射(XRD ) 和 MDI 碧玉被描绘 5.0 软件(材料数据公司，加州利物浦) 。扫描电子显微镜学(SEM ) 和电子探针微量分析(EPMA ) 结合了精力散的光谱学(版本) 被利用调查形态学特征。结果证明那个 Ti2AlN 阶段与靠近、薄片状的结构是开发得好的。谷物与 3 5 μ m， 8 10 μ m 的厚度和伸长的尺寸的尺寸是像板的。Ti2AlN 的密度被测量是 4.22 g/cm3，它到达 97.9% 它的理论价值。Ti2AlN 谷物的分发是同类的。

英文摘要：

High-purity Ti2AIN ceramic was prepared at 1300℃ by hot pressing（HP） of Ti/Ai/TiN powders in stoichiometric proportion. The sintered product was characterized using X-ray diffraction（XRD） and MDI Jade 5.0 software （Materials Data Inc, Liverpool, CA）. Scanning electron microscopy（SEM） and electron probe micro-analysis（EPMA） coupled with energy-dispersive spectroscopy（EDS） were utilized to investigate the morphology characteristics. The results show that Ti2AIN phase is well-developed with a close and lamellar structure. The grains are plate-like with the size of 3-5 μm, thickness of 8-10 μm and elongated dimension. The density of Ti2AlN is measured to be 4.22 g/cm^3, which reaches 97.9% of its theory value. The distribution of Ti2AlN grains is homogeneous.
