摘要
ＦｅＴｉ是具有多种用途的功能材料，以金属钛和铁为原料，在熔盐介质存在下，用固相反应通过两种方法合成ＦｅＴｉ，方法一是先把钛合成氢化钛后再与铁粉混合，通过热分解、扩散过程得到合金，方法二是直接把两种金属粉混合，再经氢化、热分解、扩散处理得到合金。实验证明，这两种合成方法是可行的，且第二种合成方法更为简便，其反应最佳条件是：吸氢温度～５７０℃，８００℃，６小时，介质ＮａＣｌ。
Intermetallic compound FeTi was synthesized from mixture of titaniun and iron powders byhydrogenation of titanium followed by thermal decomposition and solid-state diffusion.Theieaction product was identified as FeTi by its x-ray diffraction patterm and thermal behaviourby DTA technique. The intermetallic compound FeTi was obtained as a single phase at 800℃ after 6h thermo-treatment in fused NaCl.
