Study on the microstructure evolution during hot deformation of GH5188 superalloy

  • 摘要: 采用Gleeble-3800热模拟试验机研究了GH5188高温合金多道次变形和保温过程中的组织传递规律,建立了变形速率0.01~10 s−1,变形量50%,变形温度980~1230 ℃下的热加工图,探讨了单道次变形后保温时间对双道次变形组织、双道次变形后保温时间和保温温度对组织遗传性以及双道次降温变形和保温时间对显微组织的影响。结果表明:热加工图中高功率耗散率区的边界条件分别为1050~1175 ℃、0.01~0.1 s−1和1200~1225 ℃、0.01~1 s−1,低功率耗散率区的边界条件分别为975~1150 ℃、0.01~10 s−1和1150~1225 ℃、0.1~10 s−1;第一道次变形后保温时间过长不利于第二道次动态再结晶的发生;双道次变形后保温时,发生了明显的再结晶现象,随着保温时间的增加,晶粒未发生明显的长大;随着第二道次变形温度的降低,试样再结晶比例降低,保温温度越低,越不容易发生静态再结晶。
