Cutting and plastic deformation
The initial workpieces for machining processes are hafnium alloy rods or bars of round or rectangular cross-section. Casting of such workpieces is performed in a vacuum-arc furnaces, to avoid oxidation of the metal. Subsequently, these rods can be subjected to forging, cold forging or rolling. For processing using conventional equipment, if necessary, to use a furnace with controlled atmosphere, which lacked oxygen. At infringement of technology of forging of blanks hafnium crack.
Temperature range of operations of plastic deformation is:
- For rolling — 760… to 950 °C;
- For forging — 11000…1250°C
The temperature of heat treatment is not higher than 1300 °C (at higher temperatures the metal begins structural transformation).
Hafnium cutting of workpieces produced with reduced gaps between the knives (or punches/matrices), since due to increased ductility, the metal may adhere to the cutting edge of the tool. Cutting hafnium billets on mechanical equipment is not recommended.
Machining of hafnium
Most machining operations of workpieces made of hafnium on machine tools is difficult because in the process of drilling, turning, milling, etc. process must stop because the required tool set-up. Some of the best vitality show tools made from high speed steels.
Machining it is recommended to use at higher speeds, moreover, the ductility does not require powerful hardware. The main feature of all technologies of machining of hafnium — the need for swift evacuation, which when accumulation may spontaneously ignite. All sparking contacts for the same reason are subject to a thorough inspection.
