摘要
The massive gamma transformation which occurs after adequate thermal treatment in TiAl alloys with similar to48 at % Al has been investigated by EBSD analysis. A particular crystallographic relation between the gamma(m) nucleus and the adjacent alpha(2) grain has been demonstrated. The relations between adjacent gamma(m) domains have also been characterized. These results confirm previous assumptions about the mechanism of the massive gamma transformation.
