The TiAl-Cr alloys compositions were chosen from the g-phase stability region up to maximum 5 at. % chromium. The elemental powders were initially blended to desired composition of Ti-49,Al-49,Cr-2 and Ti-48,Al-47,Cr-5 (numbers indicate at. %). The ball milling process was performed in a high energy planetary mill Fritsch Pulverisette P/4 and detailed study of structure and micro-hardness changes during milling was described in .
