中文摘要:
      通过热压缩实验,研究了Cr含量为7 %和20 %的两种新型镍基合金在温度为950-1200 ℃、应变速率为0.01-10 s-1变形条件下的热变形行为,并建立了两种合金的热加工图。结果表明,Cr含量的增加显著提高了合金在低温高应变速率条件下的热变形抗力,增大了合金的热变形激活能;通过对比合金的热加工图可以看出,Cr含量的增加,使合金安全热加工范围缩小。

英文摘要:
      Hot compression tests were carried out to study hot deformation behavior of new Ni-based alloys with different contents of Cr (7 % and 20 %) in the temperature range of 950 ℃ to 1200 ℃ and strain rates ranging from 0.01 s-1 to 10s-1, and processing maps for both alloys were established. The results showed that increasing Cr content significantly enhanced the hot deformation resistance at low temperature and high strain rate, and also increased the apparent activation energy. Comparison of the processing maps of two alloys indicated that safe hot processing range was decreased with the increasing of Cr content.
