Effect of Electron Beam Power Density on the Structure of Titanium Under Non-Vacuum Electron-Beam Treatment

The structure of surface layers of titanium alloy OT4 subjected to non-vacuum electron-beam treatment with power density of the beam equal to 0.28 – 0.90 kW/cm 2 is analyzed. The microstructure of different zones of the material after the treatment and the crystallographic texture appearing in the s...

Description
Summary:The structure of surface layers of titanium alloy OT4 subjected to non-vacuum electron-beam treatment with power density of the beam equal to 0.28 – 0.90 kW/cm 2 is analyzed. The microstructure of different zones of the material after the treatment and the crystallographic texture appearing in the surface layers as a result of the electron-beam impact are studied. The microhardness of the remelted layers and of the heat-affected zone is measured. Mathematical modeling is used to obtain the distribution of the temperatures and the heating and cooling rates over cross section of the treated material.
