A process to be optimised is the precision casting of near-g TiAl components like turbochargers and valves for car and aerospace engines. Near-g TiAl alloys based on the composition Ti-48Al-2Cr-2Nb with boron addition and with controlled levels of interstitial impurities will be considered. The optimal trade-off between processing cost, the product quality and microstructure should be found.
