The invention relates to a rebound measurement method of high-strength steel containing metastable austenite phase, which belongs to the field of rebound measurement methods of high-strength steel, in particular to a rebound measurement method of high-strength steel whose microstructure contains metastable austenite phase. The method first determines that the high-strength steel has no fracture during bending forming, then determines the experimental basic data of the material through multiple groups of material experiments, and finally integrates the experimental basic data of the material to accurately calculate the rebound angle of the high-strength steel; The springback angle can be accurately calculated according to the basic data of materials and the preset forming angle, which can meet the forming requirements of high-strength steel parts. The rebound measurement method of high-strength steel containing metastable austenite phase has fast test speed, intuitive and reliable results, and is suitable for high-strength steel containing metastable austenite. The selected data: the bending angle, bending radius, steel thickness and the volume fraction of metastable austenite in high-strength steel are easy to determine, and the yield strength and elastic modulus are determined by the properties of high-strength steel; The method of the invention has simple model and intuitive and reliable results.
