Preparation and Characterization of Quaternary TiZrMnFe Gettering Compound

Abstract

The quaternary TixZr1-xMnFe gettering alloys (x =0, 0.1, 0.2, 0.3 and 0.4) were synthesized successfully by arc melting and their phase structures along with microstructures had been investigated by optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM). It showed that the addition of Ti did not change the phase structure of ZrMnFe of C14 laves phase. XRD results showed that Ti successfully replaced part of the Zr and the decrease of interplanar spacing had a linear relationship with the increase of Ti content. The success of this trial preparation provides reference for nuclear industry gettering materials.
