- Abstract
Annealing treatment is carried out for the TA2-2A12 explosive composite plate under the heating temperature of 440ºC and 480ºC with duration time of 1h, 3h, 6h and 9h respectively. The microstructure and mechanical properties of composite plate are investigated after annealing. Results show that recovery and recrystallization occurred near interface of composite plate after heat treatment. And the longer duration time is, the bigger the size of grains is. The shear strength of composite plate reaches the maximum value of 82.3MPa under the condition of 440ºC×3h. The microhardness measurement demonstrates that the mcirohardness decreases in direct proportion to the heating temperature and duration time. EDS analyses indicate that three kinds of intermetallic compounds (TiAl3, TiAl, TiAl2) formed near interface of composite plate undergone the annealing process of 480ºC×9h, 440ºC×6h, 480ºC×6h, respectively. The shear strength of composite plate decreases resulting from the formation of intermetallic compounds. Considering all of the influencing factors, 440ºC×3h is determined as the optimized annealing process in present work.
