以90%变形量的Pd40Cu合金为研究对象,进行550 ℃/60 min,650℃/30 min,650℃/60 min的热处理,分析热处理过程中的再结晶行为及组织的演变规律.结果表明:Pd40Cu合金在550 ℃/60 min热处理后为带状组织,650℃/30 min热处理后为完全再结晶且晶粒细小、分布均匀;随着保温时间的增加,再结晶晶粒发生明显的长大.热处理后,Pd40Cu合金再结晶Cube织构的含量很少,S型织构和Brass织构的含量相对来说较多.由于大变形量下合金内部的储存能较高,在550 ℃热处理后,大部分晶粒已完成再结晶转变,在升高温度的过程中晶粒尺寸增加,而织构的含量没有发生较大的变化.
Microstructure Evolution of Pd40Cu Alloy with 90%Deformation During Heat Treatment
90%deformed Pd40Cu alloy was annealed at 550℃/60 min,650℃/30 min,650℃/60 min.Recrystallization behavior and microstructure evolution during the annealing process were analyzed.The results show that the microstructure of Pd40Cu alloy is banded after annealing at 550℃/60 min,and the recrystallized grains are completely recrystallized after annealing at 650℃/30 min,and the recrystallized grains are small and evenly distribu-ted.With the increase of holding time,the recrystallized grains grow obviously.After an-nealing,the Cube texture content in the recrystallization annealing of Pd40Cu alloy is very small,while the S-shaped texture and Brass texture content are relatively large.Due to the higher storage energy of large deformation,most of the recrystallized grains finish nucleation after annealing at 550℃,and only the grain growth process is in the process of increasing the temperature.The texture content did not change greatly.
