Advanced Fabrication Techniques in Powder Metallurgy and Their Economic Implications.
Abstract
The first part of the Specialists' Meeting, which was attended by about 100 participants from nearly all NATO countries, was concerned with the production of powders. Four different processes of centrifugal atomization as the predominant powder metallurgy manufacturing technique for titanium alloys were presented. Argon and vacuum atomization of processes for nickel base superalloys were described as alternative techniques already proven in volume production. The second part of the Meeting consisted of reporting the state-of-the-art of techniques for consolidation of titanium and superalloy powders to near net shapes. All stages of the production sequence were discussed; powder handling, canning techniques, consolidation, secondary metal-working and thermal treatments. The specialists felt that a significant cost saving potential of more than 50% exists, using powder metallurgy processing compared with conventional manufacturing. Hot isostatic processing technology appears to have the most promising potential for production of high quality, lower cost aircraft components in the near future.
