Materials Examination of the Palmaria 155-MM Gun Tube - Foreign Science and Technology Project 60044.

摘要

A comprehensive materials examination was conducted on two Palmaria 155-mm self-propelled howitzer gun tubes produced at Palmaria, Italy. Both tube forgings were manufactured by Breda Fucine Co., Milan, Italy. The purpose of this examination was to establish the dimensional and metallurgical characteristics (i.e. chemical properties and mechanical properties) of the subject gun tubes. Based on the results of our examination, we conclude that the Italians (Breda Fucine Co.) have the capability of producing 155-mm gun tubes that meet both dimensional and mechanical property requirements of 155-mm gun tubes manufactured in the U.S. (Watervliet Arsenal).
