Importance of billet microstructure in the hot extrusion of 2% Ti-Hastelloy N
Abstract
The successful hot extrusion of billets of Ti-Hastelloy N (13 percent Mo, 7 percent Cr, 2 percent Ti, 0.06 percent C, 87.94 percent Ni) into tube shells and followed by cold drawing into 19-mm-OD (0.75-in.) tubing depends largely on the billet microstructure. It was imperative that the preheat annealing treatment given directly before hot extrusion be designed to uniformly dissolve most of the MC-type carbide particles. A 101.6-mm-diam x 304.8-mm-long (4 x 12-in.) billet required a preheat of 4 hr at 1533/sup 0/K.
