Abstract: The demands to increase range, rate of fire, and muzzle velocity have resulted in increased wear and erosion problems in gun tubes. To increase the service life of gun tubes, a number of ...

Abstract: Metallographic characterization is presented of thermal damage of Cr-coated steel in a fired cannon; Cr and Ta coated steel in a vented-erosion-simulator; and bulk Si3N4 in laser heating. Common ...

Abstract: Thermal damage observed at the bore of fired cannons has increased noticeably in the past decade, due to the use of higher combustion gas temperatures for improved cannon performance. Current ...

Abstract: Results from four groups of full-scale pressure vessel service simulation tests are described and analyzed using Paris fatigue life modeling. The objective is to determine how the vessel and ...
