EXTRUSION OF REFRACTORY METALS AND SUPERALLOYS.
Abstract
Three inch diameter billets of TZM plus 1.5% Cb Molybdenum, alloy tungsten alloys, superalloys (B-1900, 713-C, U-700 and Rene 41), Inconel X were extruded on an instrumented 700 Ton Experimental Extrusion Press to establish a relationship among extrusion pressures, billet material properties, and processing parameters. The following relationship was established: P equals AY plus bY 1n R plus S (cot alpha) 1n R plus 4 k L/D where P is total extrusion pressure, a and b are constants for each die angle, Y is material flow strength at temperature and strain rate of processing, R is reduction ratio, alpha is extrusion die half angle, L is billet length in container, D is container diameter, and S and k are interface shear strength in die and liner respectively.
