METastable Solidification of Novel Peritectic Structures - Studies with TRANSparent Model Alloys: ISS GO

Short Description

The present project proposal METTRANS-ISS GO complements the ongoing ESA-MAP project METCOMP and the corresponding ESA flight hardware project TRANSPARENT AL-LOYS.

It deals with the influence of solutal convection on layered peritectic solidification structures and the dynamic of solid/liquid interface morphologies close to the limit of constitu-tional undercooling.

The investigations are carried out as direct solidification experiments in a micro Bridgman-furnace using the transparent organic model system TRIS-NPG which solidi-fies metal-like.

METTRANS-ISS GO includes experimental investigation on earth at the Mon-tanuniversitaet Leoben and at ESA, and the final execution of space experiments aboard of the ISS.

The results are the basis for a fundamental understanding of peritectic pattern for-mation and its dependence on solutal convection and thus may serve to produce innovative alloys with a particular microstructure.
