THERMAL EMBRITTLEMENT OF STEEL FOR 175-MM GUN TUBES

Abstract

Sections of two 175-mm M113 gun tubes were utilized to study the development of both reversible and irreversible temper brittleness in 3 percent nickel-chromium gun steel. Relative material toughness indicated by the 100 percent fibrous transition temperature was determined on numerous groups of specimens tempered between 900 and 1200 F for various times.
