Description
Summary:Cold plastic deformation is the most economically efficient process for manufacturing semiproducts and parts from titanium alloys. However, with the exception of titanium alloys and some high-alloy beta -alloys, titanium alloys possesses a low ductility at normal temperature. Technical titanium has low strength characteristics, and beta -alloys are expensive due to the high content of costly alloying elements. The ductility of medium-alloyed ( alpha + beta )-alloys at normal temperature is low, which makes them inapplicable in the production of some kinds of semiproduct (thin sheets, foils, wire) and prevents the use of such efficient methods as cold forging, forming, bending, etc. The goal of the present work is to study the effect of heat treatment and degree of hydrogen alloying on the structure and deformability of titanium alloys at normal temperature.
