High Temperature Microstructural Stability of Si3N4 in TiAl Alloys
Alloys of Ti-50 at.% Al with (3 and 10)wt.% Si3N4 particles were prepared by a mechanical alloying-spark plasma sintering (MA-SPS) method. The matrix consisted primarily of TiAl, Ti2AlN, TiN. Si3N4 was unstable in the matrix and started to decompose forming a Ti5Si3 reaction layer on the surface of...

| Zusammenfassung: | Alloys of Ti-50 at.% Al with (3 and 10)wt.% Si3N4 particles were prepared by a
mechanical alloying-spark plasma sintering (MA-SPS) method. The matrix consisted primarily of
TiAl, Ti2AlN, TiN. Si3N4 was unstable in the matrix and started to decompose forming a Ti5Si3
reaction layer on the surface of former Si3N4 particles during sintering and heat treatment at 1373 K. |
