Hydrostatic Extrusion: The State of the Art

  • J. M. Alexander


The subject of hydrostatic extrusion has been written and talked about over the past ten years or so almost to the exclusion of any other metal working topic. Notable reviews have been given by Dr H. Ll. D. Pugh of the National Engineering Laboratory, his most recent paper being published in the Annals of the C.I.R.P.1 but perhaps his most important contributions are summarized in the Bulleid Memorial Lectures for 19652. Recently he has published also a chapter in a book on this subject3, and I and my colleague Dr Lengyel have written a book on Hydrostatic Extrusion 4 as well as a number of review articles5,6,7.
