Manufacturing Developments to Reduce Strategic Materials Usage,

Abstract

The worldwide shortages and price escalations of cobalt, titanium, tantalum and other key elements in the late 1970's instigated manufacturing development programs to reduce their usage in gas turbine engines. This paper describes several programs which provided significant results in reducing raw material requirements, that have been reduced to practice. The programs include forging and casting complex parts to near net shape, recycling of machining scrap and used parts, repair and refurbishment of damaged or worn parts, and component retirement for cause. In addition to reduction of strategic material usage, these programs have resulted in lower cost parts due to reduced material input requirements and less machining. (Author)
