Development of the Manufacturing Capabilities of the Hydrostatic Extrusion Process. Volume 2
Abstract
The purpose of the program was to develop the manufacturing capabilities of the hydrostatic-extrusion process. Specific applications studied were fabrication of wire, tubing, and shapes from relatively difficult-to-work materials such as refractory-metal alloys, high-strength steels, aluminum alloys, titanium alloys, beryllium, and other selected materials. Phase I was concerned with process optimization and Phase II with direct process application. As part of Phase I, the effects of critical process variables on pressure requirements and product quality were studied for wrought and powder materials ranging from relatively high-strength easy to work materials such as aluminum alloys and steels to the relatively more difficult-to-work materials such as Ti-6Al-4V titanium alloy and superalloys. With these materials, fluids and lubricants tended to be the factor controlling pressure requirements and product quality. With almost every material extruded the limit in extrusion ration was set by the design pressure capacity of the container except for the aluminum alloys where the limit was set more by the efficiency of the lubrication system. In the hydrostatic extrusion of brittle materials, die design proved to be the most significant factor controlling the production of sound, good quality extrusions. New die-design concepts have opened up new fields for the application of hydrostatic extrusion to brittle materials.
