摘　　要：As service conditions become more challenging and production complexity increases,there is an increasing demand for enhanced comprehensive performance of ceramic/metal heterostructures.At present,brazing technique has been widely utilized for ceramic-metal heterogeneous joints.However,the residual stress relief in these welding joints is complicated and necessary.Because metals and ceramics have different properties,especially their coefficients of thermal expansion.Welding joints exhibit large residual stresses during the cooling process.The relatively high residual stresses may significantly degrade the joint properties.For this issue,four alleviation routes were reviewed:optimization of process parameters,setting an intermediate layer,surface structure modulation and particle-reinforced composite solder.The states and distribution patterns of residual stress in ceramic-metal brazed joints were summarized,and the generation and detection of residual stress were introduced.Eventually,upcoming prospects and challenges of residual stress research on ceramic/metal heterostructures were pointed out.随着苛刻环境恶劣化和加工制造复杂难度增加,对陶瓷/金属异质结构综合性能提出更高要求。目前钎焊技术被广泛应用于陶瓷与金属异质连接,而二者焊接接头残余应力缓解非常棘手。由于陶瓷与金属的性能差异,特别是热膨胀系数的差异,钎焊接头在冷却过程中会产生过多的残余应力。较高残余应力会严重破坏接头性能。为缓解残余应力,从工艺参数优化、施加中间层、颗粒增强复合钎料和表面结构调控4种缓解途径进行评述。概述陶瓷与金属钎焊接头残余应力状态与分布规律,介绍残余应力的产生与检测,最后展望未来陶瓷/金属异质结构残余应力研究面临的机遇和挑战。
