摘要
研究了Nb10Zr铸锭预处理、锻造、轧制、热处理等工艺及Nb10Zr靶材的制备工艺。结果表明,1450℃保温90 min的铸锭预处理,可以改善锻造塑性;1 300℃径向圆周锻造、1 000℃轧制及1 200~1 450℃热处理,可以避免锻造和轧制开裂,晶粒度达到8级且组织均匀。
Pretreatment,forging,rolling and heat treatment for Nb10 Zr ingot and the preparation process of Nb10 Zr target were investigated. Experiment results showed that when the ingot was pretreated at 1 450 ℃ for 90 min,its plasticity would be improved; circular forging at 1 300 ℃,rolling at 1 000 ℃ and heat treatment at 1 200 - 1 450 ℃ could prevent the material from cracking in the process of forging and rolling. The grain size of Nb10 Zr target was of 8 grade,and the microstructure was uniform.
