NaCl Type fcc Cr Carbide Formation

Department of Materials phgsics

摘要: 用離子注入方法形成了NaCl型面心立方CrC。電子衍射確定其晶格常數為0.403nm。原位加熱到250℃左右,其電子衍射環消失,表明它是亞穩的。按Miedma形成熱計算方法計算,它的形成熱為-29.4kJ/mol,說明它可能是一個亞穩相,俄歇譜也證實這一碳化相的存在。

Abstract: A simple fcc Cr carbide was formed for the firal time by carbon ion implantation into Cr thin filma. Lattice constant determined by electron diffraction was 0.403nm. In situ annealing in TEM showed it exited upto a temperature about 250℃. The carbide phase was further confirmed by Auerg electron spectra. The meidema heat of formation was - 29.4kJ/mbl.
