Scope
Main technical content: Residual stress is a stress that exists in equilibrium within an object without external forces, characterized by three elements: magnitude, direction, and location. Residual stress in products is widely present in various components in the industrial field and has a significant impact on the manufacturing quality and service (working) reliability of product components. With the parallel development of technology, residual stress in products can be accurately quantified through non-destructive testing and localized quantitative control, laying the foundation for effective and rational utilization of residual stress. Residual stress is an important parameter in the performance of product components, which has a significant impact on the strength, fracture resistance, fatigue strength, dimensional stability, and corrosion resistance of product components. It has become an important basic parameter for describing the performance of product materials and components, similar to geometric tolerances, surface roughness, and material hardness. Clear requirements should be specified in the drawing stage of product design to enable effective identification and control of residual stress during product manufacturing, acceptance, and service, thereby further improving and ensuring product quality and service safety. There are two main ways to generate product stress: one is stress generated during processing, and the other is stress generated during service (working). These two ways of generating residual stress are inevitable stages in product formation and existence. There are three types of residual stress generated during product processing: 1. Subtractive processing (including: turning, milling, planing, grinding, boring, drawing, rolling, and inserting). 2. Additive processing (including: additive manufacturing (or 3D printing), casting, molding, heat treatment, plating, welding, and bonding). 3. Deformation processing (including: forgi
