A COMPARISON OF THE TOUGHNESS CHARACTERISTICS OF D6 AIR AND VACUUM MELT MATERIAL,

Abstract

An investigation was made into the relative toughness properties of D6 air melt and D6AC vacuum melt material. This was accomplished to determine which type of material would be better suited for use in the construction of solid propellant motor cases. Standard smooth tensile and notched tensile tests were performed on both materials over a range of thickness and temperatures. The smooth tensile test indicated very little difference between the D6 air and D6AC vacuum melt material. The notched tensile test, however, indicated that the D6AC vacuum melt material possesses much better toughness properties than does the D6 air melt material. (Author)
