Abstract:

An investigation was conducted at the Research Directorate, Weapons Laboratory, USAWECOM, to determine the erosion and wear characteristics of a conventional-cast gun tube material, Haynes Stellite Alloy No. 21, HS-21, and to relate mechanical properties and structural aspects of the alloy to these characteristics. A significant portion of this effort was applied to the construction and development of a special wear-test apparatus capable of variable load and sliding speed, ultra-high vacuum, gaseous environments, and elevated temperature testing.
