VARIATION IN MECHANICAL PROPERTIES OF TEMPERED MARTENSITE GUN STEEL.

Abstract

The purpose of the investigation was to determine the level and reproducibility of mechanical properties in the present gun tube materials, quenched to a uniform microstructure of 100% martensite and tempered to yield strength ranges of 140-160,000 psi and 160-180,000 psi. Reheat treatment of small sections of gun tube material results in a finer, more uniform martensitic structure than existed in the original tube. These results should represent the minimum variation in mechanical properties that can be expected in our present gun tube material. (Author)
