Elastic, Strength, and Stress Relaxation Properties of A723 Steel and 38644 Titanium for Pressure Vessel Applications

Abstract

Mechanical properties of a high strength steel and a titanium alloy have been measured for application to compound cylinders of steel and titanium subjected to elevated temperature. Results are presented from tests and analyses of elastic and failure strength, stress relaxation, fracture toughness, and microstructure and microhardness. Conclusions are drawn regarding the suitability of the two materials when subjected to conditions typical of cannon fabrication processes and service loading. Keywords: Tensile strength; Lightweight.
