用热槽方法研究了镍和316L奥氏体钢在临界应变后选择性生长过程中晶界能级的变化。结果表明，平均晶格能量γGb随退火温度的升高而增大，随平均晶粒度d的增大而增大。这些变化可以用生长过程中晶格间的反应来解释。发生增长的关键条件是%dγGB必须小于(γGB/d)dd。MST/246
Changes in the energy of a grain boundary (GB) population during selective grain growth in nickel and 316L austenitic steel after critical strain have been studied using the thermal grooves method. It was found that the average GB energy γgb increases as a function of the annealing temperature, and consequently as a function of the average grain size d. These changes are interpreted in terms of reactions between GBs during growth. The critical condition for growth to occur is that dγgb must be less than (γgb/d) dd. MST/246
