【摘要】：无磁性、高强度Ni-9.3at%W(Ni9W)合金由于其较低的层错能,难以通过传统的轧制及再结晶退火得到强立方织构。本工作采用熔炼制坯路线,结合均匀化退火和中间再结晶退火的方法得到了晶粒尺寸细小,合金元素W均匀分布的Ni9W坯锭,通过总变形量为99%的轧制,中间引入四次轧制间回复退火得到了厚度为80μm的Ni9W轧制基带,最后采用两步再结晶退火的方式得到了再结晶立方织构含量为80.2%(10o)的Ni9W合金基带。
[Abstract]:Because of its low stacking fault energy, it is difficult to obtain strong cubic texture by traditional rolling and recrystallization annealing in non-magnetic and high-strength Ni-9.3at%W (Ni9W) alloys. In this work, Ni9W billet with fine grain size and uniform distribution of alloying element W was obtained by melting process, combining homogenization annealing and intermediate recrystallization annealing, and the total deformation was 99%. The Ni9W rolling band with thickness of 80 渭 m was obtained by four times interrolling recovery annealing. Finally, the recrystallized cubic texture 80.2% (10o) Ni9W alloy substrate was obtained by two-step recrystallization annealing.
