Abstract

This paper focuses on the development of microstructure of TiNb 40 alloy after severe plastic deformation. Primary billets (blocks) are Ti alloy cast with 40% Nb mass which are exposed to a combined two-stages severe plastic deformation method, including abc-pressing and multi-pass rolling in grooved rolls . An area of less than 0.3 micron grains is about 6% of the total area. It plays a strong role for improving the strength of the material. Microhardness of the alloy increased to 2300MPa. The small-angle grain boundaries (less than 15 °) of the alloy account for 61.1% after the combined processing . It is shown that a relatively large amount of micron grains and subgrains were produced in the processing of the alloy.
