Nanometre-scale chemical compatibility of TiAl with Al2O3, TiB2 and TiC

Preliminary results are presented for the nm-scale compatibility of the TiAl alloy matrix with Al2O3 and TiB2, whose interfaces with TiAl are predicted to be stable, and TiC, which is predicted to be unstable; a thin-film sandwiching method is employed. The results obtained for the former two cases...

Description
Summary:Preliminary results are presented for the nm-scale compatibility of the TiAl alloy matrix with Al2O3 and TiB2, whose interfaces with TiAl are predicted to be stable, and TiC, which is predicted to be unstable; a thin-film sandwiching method is employed. The results obtained for the former two cases differ from those of bulk diffusion studies. (AIAA)
