摘要：
In the present study an ultra high strength armour steel was austenatised at 910 degrees C followed by tempering at 200, 300, 400, 500 and 600 degrees C. After heat treatment the properties of tensile strength, ductility, charpy impact strength, hardness and microstructure were evaluated from the mechanical tests and metallographic analysis respectively. The ballistic behavior of the heat-treated plates was evaluated impacting against non-deformable hard steel core projectiles at 840 +/- 15 m/s at normal angle of attack. The changes in the microstructure and mechanical properties with heat treatment have been correlated with ballistic performance of the steel. Experimental results showed that 200 degrees C tempering gives the best ballistic performance. (C) 2009 Elsevier Ltd. All rights reserved.
