Production of ingots of titanium
The main methods of manufacturing of intermediate billet of titanium and its alloys is still forging to produce forgings and slabs, and also for rolling of round billets. The analysis shows that only 12−15% of the deformed semi-finished products from titanium or titanium alloys is obtained directly from ingots by extrusion, forging or rolling. These products put a massive profile, large bars and plates, and heavy forgings.
New methods of melting
In the foundry they allow you to obtain a flat, square and round bars of various parameters, including small cross section, which led to the change of the ratio of semi-finished products made directly from titanium ingots and their intermediate blanks. It should be noted also that the problem is not limited to obtaining the dimensional blanks to final forming. New methods allow to obtain the desired structure of the alloy for a wide range of products.
In the manufacture of rods of small section and wire billets for thin plates and sheets, extruded and rolled tubes and profiles, as well as small stampings does not require the use of special operations aimed at the formation of a regulated structure, because in the further processing of these blanks is still undergoing the deformation necessary to change the structure. In the manufacture of the same large diameter bars, thick plates, thick-walled profiles and pipes, of medium and large forgings intended for the manufacture of highly loaded parts provide for the conduct of special operations. Otherwise, when further deformation or even impossible to provide the desired structure and mechanical properties, or require additional time-consuming operation.
An important principle of hot working of titanium alloys is the choice of modes of heating and deformation. They must comply with the technological plasticity of the alloy, temperature and thermal conductivity, the necessary stress for deformation, kinetics of oxidation and hydrogen saturation — that is, to consider all the regularities of structure formation. Data for thermal conductivity is important for establishing the minimum time of heating of billets, their deformation and heat treatment. This time at t° 1000 °C is approximately equal to 40 seconds at a 1 millimeter thickness, and 60 seconds at lower temperatures. With these data and determined the minimum cooling time of billets of different cross sections at the end of the operation.
