On the basis of results of modelling  a series of experiments is conducted for electron beam treatment (EBT) of titanium alloy VT6, VT20, VT22, and VT3-1 ingots 400 and 600 mm in diameter. As a result of this work parameters are established for titanium alloy ingot EBT making it possible to remove surface defects effectively with retention of the chemical composition of the melted layer at the level of standard specifications providing good surface quality and an increase in the yield of finished metal by up to 6%.
