ZONE REFINING OF CEMENTED TUNGSTEN-BASE ALLOYS.

Abstract

A series of experiments was made to scale-up efforts to produce large tungsten sheets. A 600-lb block of W-Ni-Fe powder was prepared by hydrostatic pressing. Twelve-inch square slabs (one inch thick) were cut from this block and sintered. Some were warm rolled and subjected to zone refining treatment by electron beam heating. The details of the experimental results are discussed. (Author)
