The traditional continuous annealing process for iron-based alloysIron-based alloys has basically matured, and its production efficiency is difficult to further improve. However, the rapid heat treatmentRapid heat treatment process heats up to the target temperatureTemperature and rapidly cools down, which can refine the grain size, control the microstructureMicrostructure and texture, and obtain high comprehensive mechanical propertiesMechanical properties while improving production efficiency. This article provides a comprehensive analysis of the patent applications, applicants and applicant's research direction on rapid heat treatmentRapid heat treatment of iron-based alloysIron-based alloys, providing patent technical support for improving the comprehensive performance of iron-based alloys through rapid heat treatmentRapid heat treatment technology. It also summarizes the development trends of rapid heat treatmentRapid heat treatment technology for iron-based alloys: (1) Expansion of applied area of rapid heat treatmentRapid heat treatment technology. (2) Coupling with the third-generationHigh-strength steel high-strength steel heat treatment technologies. (3) Coupling with industrial continuous production technologies.
