Abstract:

We found that an alloy containing a minimal amount of rare earth elements in aluminum significantly improves the sinterability of aluminum in a pressureless state. In this presentation, we dynamically observed the sintering process and evaluated in detail how the sintering progressed. Liquid phase sintering is achieved by the liquid phase that is produced when a minimal amount of rare earth element dissolves in aluminum below the melting point of aluminum.
