N2 - The elastic constants of single-crystal gamma-TiAl(Ti-56.0 at.% Al) have been measured from 4 to 298 K. The values at 298K agree with those recently reported by He, Schwarz, Migliori and Whang. c12 and c13 are virtually temperature independent while the other elastic constants normally decrease with increasing temperature. The values extrapolated to 0 K are c11=187GPa, c33=182 GPa, c74.8GPa, c13=74.8 GPa, c44=109GPa and c66=81.2 GPa. The elastic anisotropy factors A1=c662/(c11-c12), A2=4c44/(c11+c33-2c13) and c44/c66 at 0K are virtually equal to those at room temperature.
