Abstract

In this study, the kg-class Ni-Al alloy fabrication process at low temperature was developed from the physical mixture of Ni and Al powders. The AlCl3 as an activator was used to reduce the temperature of alloy synthesis below the melting temperature of Ni and Al elements (<$500^{\circ}C$). Mixed phase of Ni3Al intermetallic and Ni-Al solid-solution were identified in the XRD pattern analysis. Furthermore, from the analysis of SEM and particle size analyzer, we found that the particle size of synthesized alloy powders was not changed compared to the initial size of Ni particle after the formation of alloy powder at $500^{\circ}C$. In the creep test, the anode (which was fabricated by the prepared Ni-Al alloy powders in this study) displayed the enhanced creep resistance compared to the conventional anode.
