摘要

Based on the local annealing process with induction heating for the A286 alloy sleeve of the blind bolt, a mathematical model is built to analyze electromagnetic-thermal coupling. Influence factors, such as frequency and current, are investigated and analyzed using finite element method on temperature distribution and length of the annealing zone in induction heating. The experiment on local annealing of the sleeve is then carried out with the optimal parameters of annealing process. Results show that temperature distribution designed in annealing zone is in a good agreement with the hardness distribution of the sleeve. The local annealing process validated by wrinkle of the sleeve under axial compression is feasible.
