SCOPE 1.1 Scope. This specification covers a weldable wrough
2、t titanium alloy structural armor plate in nominal thicknesses from 0.125 - 4.0 inch, inclusive. Ballistic data requirements for nominal thicknesses of 0.125 to 0.249 inch, inclusive are not available for this Revision. 1.2 Classification. Wrought titanium alloy armor should be of the following clas
3、ses as specified (see 6.2). 1.2.1 Class 1. Class 1 is equivalent to material specified by previous revisions of MIL-A-46077, which is an Extra Low Interstitial (ELI) grade. 1.2.2 Class 2. Class 2 is equivalent to material specified by MIL-T-9046J, AB-1 composition. 1.2.3 Class 3. Class 3 permits a h
4、igher oxygen level which would be suitable for applications where maximum ductility and toughness are not necessary, such as appliqu. 1.2.4 Class 4. Class 4 permits Al, V, & Fe compositions different from the conventional Ti-6Al-4V alloy. Comments, suggestions, or questions on this document should b
