Texture evolution of tungsten materials during recrystallization
Some functional and structural performance of tungsten (W) are related to its texture characteristics. Usually, W serves in high temperature and may undergo recrystallization. Thus it’s necessary to evaluate the recrystallization texture of W. In our previous studies, pure W (PW) and W-1.0wt%La _2 O...

| description | Some functional and structural performance of tungsten (W) are related to its texture characteristics. Usually, W serves in high temperature and may undergo recrystallization. Thus it’s necessary to evaluate the recrystallization texture of W. In our previous studies, pure W (PW) and W-1.0wt%La _2 O _3 (WL10) were deformed via unidirectional rolling (UNR), cross rolling (CRR) and clock rolling (CLR) with 80% reduction. In the present paper, PW-UNR, PW-CRR, PW-CLR and WL10-UNR were subjected to annealing at 2073 K for 2 h to achieve recrystallization and figure out the evolution mechanism of recrystallization texture in W materials. Besides, the effect of La _2 O _3 on recrystallization texture of W was discussed. The results indicated that the fiber textures in rolling state were transformed into isolated textures after recrystallization. {001}〈uvw〉 isolated texture formed in the recrystallized W may be mainly resulted from the texture inheritance. {113}〈361〉 isolated texture formed in the recrystallized WL10-UNR may be attributed to the orientated growth of {113}〈361〉 grains with high grain boundary mobility facilitated by La _2 O _3 . Generally, isolated textures near θ -fiber were strengthened while γ -fiber was weakened for W during recrystallization, which is an effective method to achieve W with more {001} and less {111} textures. |
