Radial-Shear Rolling of Titanium Alloy VT-8 Bars with Controlled Structure for Small Diameter Ingots (≤200 mm)

  • Published:
Metallurgist Aims and scope

Experimental studies are made of the technological possibilities of radial-shear rolling in order to prepare titanium alloy VT-8 bars with a controlled structure and mechanical properties for small diameter ingots. The effects of rolling routes and thermal deformation conditions on macro- and microstructure are studied for the bars obtained, and also on mechanical properties. The possibility is demonstrated of preparing bar with structure and properties satisfying standard specifications for bars 200 mm in diameter solely by radial-shear rolling. A production scheme proved by experiment in RSR mills may be proposed as a basis for high-tech mini-rolled product manufacture with a flexible production program.
