概要
- 論文の詳細を見る
Ti--Fe nanoparticles were prepared by pulsed wire discharge (PWD) using iron (Fe) and titanium (Ti) twisted wire in Ar gas at a pressure of 100 kPa. The content of Fe ($C_{\text{Fe}}$), which was changed from 0 to 100 wt %, was controlled by adjusting the number of Ti and Fe wires in the twisted wire. From the X-ray diffraction, the phase of the prepared nanoparticles changed from $\alpha$-Ti to $\beta$-Ti, FeTi, Fe2Ti, Fe(Ti), and Fe with increasing $C_{\text{Fe}}$. FeTi nanoparticles were obtained at approximately $C_{\text{Fe}} = 30$ wt %. From these results, the phases of the prepared Ti--Fe nanoparticles were controlled by adjusting the content of Fe in the twisted wire.
