Abstract: Ceramics have shown advantages such as high strength and corrosion resistance. The structures achieved by joining ceramics with metals could fulfill the growing requirements of lightweight, high temperature and corrosion resistance by aerospace engineering, nuclear and chemical engineering. However, due to the mismatch between the thermal expansion coefficient between ceramics and metals, high residual stress could be generated in the joint during the cooling process and deteriorate the reliability of the joint. This paper reviews the research progress of the three most commonly used residual stress controlling methods for ceramic-metal joint, including composite brazing alloy method, interlayer method and ceramic surface design method. The development of the newly invited methods such as femtosecond laser welding and flash joining via local heating is also introduced. The methods suitable for measuring the residual stress in ceramic-metal joints and the corresponding theory are discussed. The research progress on the measurement of the residual stress in ceramic-metal joints is summarized. The future development of the control and measurement of the residual stress in ceramic-metal joints is presented.
