摘要：

Hot compression behavior of TiC-Al2O3/Al composites was studied using the Gleeble-1500 system at a temperature range of 300-550 A degrees C and at strain rate range of 0.01-10.00 s(-1). The associated structural changes were studied by TEM observations. The results show that stress level decreases with deformation temperature increasing and strain rate decreasing, which can be represented by a Zener-Hollomon parameter in an exponent-type equation with hot deformation activation energy Q of 172.56 kJ center dot mol(-1). Dynamic recovery occurs easily when strain rates are less than 10.00 s(-1). Dynamic recrystallization can occur at strain rate of 10.00 s(-1).
