3rd Progress Meeting ESA-MAP "GRADCET" at DLR, Cologne-Porz
The third progress meeting of the ESA MAP GRADECET (GRAvity Dependence ofColumnar to Equiaxed Transition in peritectic Ti-Al alloys) was held at theInstitute of Materials Physics in Space, DLR, Cologne-Porz, on 14th June 2012.12 scientist from Germany, Ireland, the Slovakian Republic, and Hungary aswell as one representative each of ESA and Astrium GmbH participated in themeeting. Scientific and technical issues in the area of solidification in anddiffusion of Al-Ti alloys used as in high-temperature applications aslightweight alloys have been discussed.
The GRADECET project aims to investigate the influence of gravity onmicrostructure formation and segregation in peritectic Al-Tialloys. Experiments are to be carried out under microgravity, 1-g and hyper-g(up to 20g) conditions. The GRADECET project consolidates and complementsmicrogravity investigations of Al-Ti alloys carried out in the framework ofthe integrated project IMPRESS.
During the progress meeting the preparation of solidification experiments forthe next sounding rocket campaign MAXUS-9 (scheduled autumn 2014) and on theESA large diameter centrifuge in Noordwijk have been discussed. A subsequentprogress meeting is planned in Budapest, Hungary, in October 2012.
