Development of a Stress Corrosion Cracking Test for Armor Alloys

Abstract

A stress corrosion test has been developed for use with high-hardness armor alloys; it is self-loaded, and it can be used with any armor plate thickness. Initial trials have proven the validity of the test method, although several refinements are recommended. Further study is needed to determine whether or not the test method can be applied to specification and qualification test procedure. Data produced to date on one plate of XAR-30 high-harness steel armor show that it is very susceptible to stress corrosion with KIscc) values from 15 to 19 ksi (sq root of inch).
