Development of a Fabrication Process for Large Cylinders from Mixtures of Spherical Powders of High Strength Aluminum and Magnesium Alloys.
Abstract
Two fabrication processes for the production of cylindrical shells approximately 6-inch 0.D x 1/2-inch wall made from mixtures of high strength aluminum alloy and magnesium alloy powders were investigated. The first method consisted of a sequence of consolidation, upsetting and back extrusion. This approach did not yield a sound product. The second method consisted of the direct extrusion of a heavy wall tube. This approach was shown to be feasible and to produce sound high strength components. Reduced scale extrusions of rods and tubes were carried out and led to the design of a full scale fabrication process. (Author)
