EXTRUDING AND DRAWING MOLYBDENUM TO COMPLEX THIN H-SECTION
Abstract
Sixteen H-shaped extrustions (14 TZM and 2 stainless) were made with new support tooling. No failure or distortion occurred in the tooling, regardless of liner pressure up to 237,000 psi. Reasonable quality and dimensional runout were found in TZM extrusions at a reduction ratio of 43:1 from 3200F billet temperature with the use of flame-sprayed zirconia dies. Similar extrusions from 3350F were poor. The use of pressed and sintered solid zirconia nibs was demonstrated successfully for the extrusion of 'H' shapes. Dimensional runout for both stainless and TZM was remarkably good and liner pressures were lower than that required for extrusions with segmented, coated dies.
