Automotive and aerospace industries are searching for new high-temperature structural materials with improved properties (especially resistance to oxidation, thermal stability and mechanical properties) in combination with low density. Ti-Al-Si alloys fulfill these requirements, but they are very difficult to prepare. In this work, we propose technology including Self-propagating High-temperature Synthesis (SHS), milling and following consolidation by Spark Plasma Sintering. The technology has been tested on the TiAl20Si20 alloy. Special attention was paid to microstructure and phase composition, and their changes depending on the processing stage.

Keywords: Intermetallics, Powder Metallurgy, Self-propagating High-temperature Synthesis, Spark Plasma Sintering
