摘要：
New 7XXX alloys having improved ballistics performance are disclosed. The new alloys generally are resistant to armor piercing rounds at 2850 fps, resistant to fragment simulated particles at 2950 fps, and are resistant to spalling. To achieve the improved ballistics properties, the alloys are generally overaged so as to obtain a tensile yield strength that is (i) at least about 10 ksi lower than peak strength and/or (ii) no greater than 70 ksi.
