| Abstract Scope |
While literature exists on the mechanical properties of aluminum intermetallics, thermodynamic data for aluminum intermetallic compounds are lacking for the solid state and non-existent in the liquid. This invites guesswork during the molten state processing of aluminum alloys that contain compound forming intermetallics such as titanium. A method for studying various melt properties of aluminum intermetallics is therefore investigated, inspired from prior work on molten oxides, sulfides, and metals. This work reports a possible use of sintered pellets of aluminum intermetallics (such as TiAl3) in a floating-zone optical furnace. Preparation methods suitable for intermetallic samples and visual observations of the melting behavior and stability of the corresponding droplets are reported. In-situ observation of stabilized intermetallic melts informs thermodynamic properties such as melting temperature, density, or surface tension, along with solidification features. |
