Abstract
Influence has been studied of high-temperature annealing and heating by the welding arc on the processes of formation of crystallographic texture in the HAZ of sheet molybdenum alloys TsM-10, TsM-12 and MI-5. It is shown that in a low-alloyed molybdenum alloy TsM-10 the initial deformation texture of (001) [110], (112) [110] and (111) [211] type is practically preserved in the HAZ and weld metal. In alloyed molybdenum alloys TsM-12 and MI-5 the initial deformation texture of (001) [110], (001) [100] and (111) [211] type in the HAZ is gradually transformed into crystallographic texture of (111) [112] and [110] type, and this texture type is preserved in the weld metal.
Keywords: crystallographic texture, pole figures, welded joints, molybdenum alloys, temperature, annealing
