【摘要】:無(wú)磁性、高強(qiáng)度Ni-9.3at%W(Ni9W)合金由于其較低的層錯(cuò)能,難以通過(guò)傳統(tǒng)的軋制及再結(jié)晶退火得到強(qiáng)立方織構(gòu)。本工作采用熔煉制坯路線,結(jié)合均勻化退火和中間再結(jié)晶退火的方法得到了晶粒尺寸細(xì)小,合金元素W均勻分布的Ni9W坯錠,通過(guò)總變形量為99%的軋制,中間引入四次軋制間回復(fù)退火得到了厚度為80μm的Ni9W軋制基帶,最后采用兩步再結(jié)晶退火的方式得到了再結(jié)晶立方織構(gòu)含量為80.2%(10o)的Ni9W合金基帶。
[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.
