Present issues of technology and economical efficiency of production of billets from nanostructured materials

Development of modern technology of billet production from nanostructured materials is an important direction of research in the field of increasing mechanical properties of commercially pure titanium. The most promising area where the unique properties of alloy titanium grades can be applied is modern medicine and implantology. At the current stage of development the search for more reliable materials for making implants, prothseses, and new technological devices replacing the lost organs and limbs is necessary. At present the light and strong titanium alloys are used for this. But the solution for optimal relation of economical efficiency of production of high-tech billets and high requirements for the material quality and operational properties of components has not been yet found. The choice of stamping technology is thus important. The modern economical situation favours fast changing of nomenclature and decreasing the batch size of ready parts. To increase production efficiency and decrease the number of stages of technological process and equipment, in particular of the expensive die tooling, combined stamping processes, viz. cold die forging are often used. Economical profitability of a batch of parts for cold die pressing is estimated to 3000-10000 pieces depending on the component manufacturability and durability of stamps, but in some cases the batch of 500 pieces may be efficient.
