Abstract: Quenched and partitioned(Q&P) steel has the characteristics of low cost, good properties, and relatively simple process, and becomes a key research object of the third generation of advanced high strength steel(AHSS). C, Si and Mn elements are the basic alloying elements of the Q&P steel, which have a significant impact on the microstructure and properties of the Q&P steel. Nowadays, most of the research is based on C-Si-Mn system partitioned steel. The production process of the Q&P steel is introduced, the effect of alloy elements on the microstructure and properties of the Q&P steel is clarified, as well as the relationship between the microstructure and mechanical properties of the Q&P steel. The focus is on the influence of process parameters on microstructure and properties of the Q&P steel, and prospects for the development of the Q&P steel are made.

Key words: Q&P steel, production process, alloy elements, process parameters, microstructure, mechanical properties
