摘要：

The strength (sigma(b), sigma(0.2)), ductility (delta, psi) and impact toughness (sigma(k)) of TC4 alloy annealed at 940, 960, 980 degrees C and cooled at different cooling rates after 980 degrees C annealing were tested by tensile tests at room temperature and impact tests at room temperature. Combined with metallography and fractography, the influence of annealing temperature and cooling rate were studied. The results show that the strength, ductility and impact toughness decrease with the increasing of annealing temperature; however, the strength increases, but the ductility and impact toughness decrease with the increasing of cooling rate.
