Thermomechanical Processing of some Heavy Alloys from the System W-Ni-Fe through Rotary Forging


Article Preview

The goal of present work was to study the possibility to produce bars from heavy alloys based tungsten through rotary forging. For the experiment there were selected two compositions from the system W-Ni-Fe (90, respectively 93 %W/wt., Ni/Fe ratio = 7/3). From the two compositions there were prepared samples by conventional route of liquid phase sintering, followed by thermal treatment in a neutral atmosphere (N2, Ar) and by rotary forging with different reduction degree.
