Ni-5%W合金基带的辊到辊再结晶(英文)

Recrystallization of Ni-5%W Alloy Substrates by Reel-to-Reel Method

基于轧制态Ni-5%W(原子分数)合金基带短样品在不同温度退火的结果,对Ni-5%W合金长带进行了辊到辊退火处理。分析不同温度下退火后的硬度,通过X射线极图法评价再结晶织构,采用光学显微镜分析基带的微观结构,讨论退火温度对再结晶织构的影响,考察短带与长带再结晶织构的差异。结果发现:长带和短带都具有很强的立方织构。

Cold rolled Ni-5at%W substrates with short length were annealed at different temperatures. On the basis of the results of annealing of short length substrates,the substrates with long length were annealed by reel-to-reel method. The hardness of the annealed substrates at different temperatures was analyzed. The recrystallization textures were evaluated by X-ray pole figure and the microstructure were investigated by optical microscopy. The effects of annealing temperature on the recrystalization texture were discussed. The differences of recrystallization texture between short length substrates and long length substrates were investigated. It is found that both short length substrates and long length substrates have very strong cube texture.
