Commercial 48-2-2 TiAl powder was densified by spark plasma sintering. Fully dense materials with duplex and lamellar microstructures were obtained. An original protocol was developed to avoid carbide formation due to reactions between TiAl and graphite molds. TiAl materials with lamellar microstructures and high creep behavior were produced.

商用TiAl 48-2-2粉末的火花等离子体烧结：致密化和蠕变分析

通过火花等离子体烧结将商品化的48-2-2 TiAl粉末致密化。获得具有双相和层状微结构的完全致密的材料。最初的规程是为了避免由于TiAl和石墨模具之间的反应而形成碳化物。制备了具有层状微结构和高蠕变行为的TiAl材料。
