Feasibility Study of Columbium Alloy Castings
Abstract
The purpose of the program is to determine the feasibility of investment-casting columbium alloys. Thirty-four castings are scheduled to be produced, using consumable-electrode arc-melting and tungsten interfaced molds to prevent mold-metal reaction. Phase I of this program concerns the optimization of mold design and preheat temperature. Phase II envisages the production of sound test specimens, followed by coating, and an environmental and mechanical testing effort.
