中文摘要:
      使用室温压缩变形与再结晶退火处理研究了Inconel 625高温合金冷变形及再结晶行为,采用EBSD技术分析冷变形过程中的应变分布、晶粒尺寸变化、组织与织构演变,分析冷变形Inconel 625合金再结晶过程中再结晶分数、晶粒尺寸、组织及织构演变。研究表明,Inconel 625合金在变形量为35%~65%时具有良好的塑性,随着变形量的增加,晶粒尺寸减小,应变分布越均匀,{111}<112>织构和{110}<001>织构逐渐减弱,而{001}<110>织构和{112}<111>织构略为增强。冷变形Inconel 625合金再结晶退火处理后,随着退火温度与保温时间的升高,再结晶分数增大;随着变形量的增大,Inconel 625合金发生完全再结晶时温度减小,且发生完全再结晶时的晶粒尺寸变小,变形量为35%时,再结晶过程主要是{112}<111>织构{123}<634>变形织构转变为{110}<112>织构、{001}<100>织构与{124}<211>织构。随着变形量增加到50%及65%时,冷变形产生的{123}<634>织构在再结晶过程中转变成了{124}<211>织构。

英文摘要:
      The cold deformation and recrystallization behavior of Inconel 625 superalloy were studied by using compression deformation at room temperature and recrystallization annealing. The strain distribution, grain size change, microstructure and texture evolution during cold deformation, as well as recrystallization fraction, grain sizes, microstructure and texture evolution of cold deformed Inconel 625 superalloy during recrystallization annealing were analyzed by EBSD technique. Studies have shown that Inconel 625 superalloy has good plasticity when the deformation is 35%~65%. With the increase of deformation, the grain size decreases and the strain distribution is more uniform, {111}<112> texture and {110} <001> texture is gradually weakened, while the {001}<110> texture and the {112}<111> texture are slightly enhanced. After recrystallization annealing treatment of cold deformed Inconel 625 superalloy, the recrystallization fraction increases with the increase of annealing temperature and holding time. With the increase of deformation, the annealing temperature decreases when complete recrystallization with finer grains occurs. When the deformation is 35%, the recrystallization process is mainly {112}<111> texture and {123 <634> texture transformed into {110}<112> texture, {001}<100> texture and {124}<211> texture. With the increase of deformation amount to 50% and 65%, the {123}<634> texture produced by cold deformation transforms into {124}<211> texture during recrystallization.
