Development of SPD Technologies and Establishment of a Production Line for Rod-Shaped Semiproducts out of Nanostructured Titanium for Medical Application

摘要

The paper reports on the investigation results for the criteria required for estimation of the SPD technologies. It has been demonstrated that one of the important criteria is specific surface area of the deformation zone, which enables considering the scale factor during processing and predicting the properties of the processed semi-products and items. Practical use of the results of conducted studies is demonstrated on the example of establishment of a production line for high-strength nanostructured semi-products from CP Ti for medical application.
