A Numerically Based Optimization of a Near-gamma TiAl Precision Casting Process
Investigator: prof. RNDr. Antonín Dlouhý, CSc.
Number of Project: OC 526.60
Agency: Ministry of Education, Youth and Sports
Duration: 01. 01. 2002 - 31. 12. 2005
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.
