    Abstract:

    It is difficult to obtain a sharp cube texture through the traditional cold rolling and recrystallization annealing procedure in the non-magnetic and high yield strength Ni-9.3at%W (Ni9W) alloy due to its low stacking fault energy. In this paper, a Ni9W ingot with fine grain and homogenized tungsten distribution was prepared by the conventional metallurgy technique combined with homogenization annealing and intermediate recrystallization annealing. The rolling substrate with 80 μm thickness was obtained through intensive cold rolling and four-time intermediate recovery annealing. The total thickness reduction was 99%. A fraction of 80.2% (<10°) of cube orientation was measured for the Ni9W alloy tape through the two-step recrystallization annealing method.
