The main methods of production of intermediate products from titanium and its alloys are still forging - for forgings and slabs, and rolling for round billets. Analysis shows that only 12-15% of deformed semi-finished products from titanium or titanium alloys are obtained directly from ingots by pressing, forging or rolling. Such products are massive profiles, large bars and plates, and heavy forgings.

New melting methods

In foundries, they allow getting flat, square and round ingots of various parameters, down to the smallest cross section, which has led to a change in the ratio of semi-finished products made directly from titanium ingots and their intermediate billets. It should also be noted that the task is not limited to obtaining an initial measured billet for the final shaping. New methods make it possible to obtain the necessary alloy structure for the widest range of semi-finished products.

Special operations

The production of small rods and wires, blanks for thin plates and sheets, extruded and rolled tubes and sections, as well as small forgings does not require any special operations to give them a defined structure, since they will be deformed for the purpose of changing their structure during subsequent processing. The production of large diameter bars, thick plates, thick-walled profiles and tubes, medium-sized and large forgings for the production of highly stressed components requires special operations. Otherwise the desired structure and mechanical properties either cannot be achieved during subsequent deformation or additional time-consuming operations are required.

Processing principles

An important principle for heat treatment of titanium alloys is the selection of heating and deformation modes. These regimes must match the alloy's technological ductility, temperature and thermal conductivity, the required deformation forces, oxidation kinetics and hydrogen saturation - that is, they must take into account all regularities of structure formation. Data on thermal conductivity are important for establishing the minimum heating time of the workpieces, before deformation and heat treatment. This time at 1000 °C is approximately 40 seconds per millimeter of thickness, and 60 seconds at lower temperatures. With the help of these data is determined and the minimum cooling time for blanks with different sections at the end of the operation.
