FLOW TURNING OF TUNGSTEN ALLOY SHEETS

Abstract

The state-of-the-art of production of large W rings and the flow turning of W shapes is reviewed. The flow turning process is discussed and a comparison is made between conventional rolling and flow turning as a process for making sheet. Although fairly extensive work on the fabrication of W cones and nozzles was reported, only 2 organizations indicated experience with the manufacture of W cylinders by flow turning. Production of Mo alloys is presented. Commercially available W alloys are briefly discussed and unalloyed W was chosen for this program on the basis of known fabricability and acceptable high temperature properties. Methods for preparation of the 12-in diameter starting blanks are presented. Sintering and ring rolling, and sintering, rolling, forming, and joining were chosen as the most promising techniques for starting blank preparation. (Author)
