Abstract:

Four billets of TZM1.5Nb were extruded during the reporting period using 41 and 61 ratios and temperatures of 2800 and 3200 F. Die angles of 60 degrees and 90 degrees were also used. Lower extrusion tonnages were required to extrude through 60 degree angle dies than through 90 degree angle dies. Fourteen chromium alloy, fifteen niobium alloy, seven pure copper, five tantalum alloy, one tungsten and thirteen tungsten alloy were extruded for other agencies. Twenty-four of the above billets were extruded for the Air Force Materials Laboratory. Author
