The Structure and Properties of Microcrystalline and Submicrocrystalline Titanium Alloy VT1-0 in the Area of the Electron Beam Welding Seam
An investigation of the welding seam structure of micro- and submicrocrystalline specimens of VT1-0 alloy is reported. Special features are revealed in the formation of the heat-affected zone in the alloy as a result of electron-beam action due to its structural state. Particular attention is given to the role of α→β-transformations characterizing titanium alloys subjected to thermal impacts. It is found that the structural features of all welding-joint zones, considering the phase transformations, determine the character of hardness value distribution and the respective strength properties of the weld joints. A comparison is given between the structure formation in microcrystalline alloys and in welding seams formed by laser-beam welding. The welding of submicrocrystalline titanium is also compared to another high-energy impact – resistance welding.
