Heat treatment technology is an important field related to material science and engineering. It is important for purposes such as strengthening and hardening materials, preserving and restoring structure, improving wear resistance and corrosion resistance, manufacturing parts and special forms, and curing defects. With the development of science and technology, the purpose of heat treatment has expanded and diversified, which has sufficient basic theoretical knowledge at the same time, it is also necessary to have practical heat treatment experience and skills. In order to ensure the quality of the workpiece in production and processing, and to save the cost of heat treatment, it is necessary to accurately analyze and predict the performance of the work piece after heat treatment in advance. Therefore, heat treatment expert system and performance prediction are very necessary.
1. The Principle and Structure of Heat Treatment Expert System
Heat treatment expert system is a computer information system that can help people to solve heat treatment related problems. The knowledge base of heat treatment expert system consists of two parts, one is production knowledge base, including its regular materials, heat treatment processes, equipment and control parameters, etc.; the other is problem solving knowledge base, including know-how, experience and inference rules. Combined with computer network technology, the expert system has better diagnosis, guidance, simulation and decision-making ability. The prediction of heat treatment performance includes qualitative and quantitative prediction methods.
