Abstract

Abstract: Effect of secondary forging deformation on microstructure, precipitation and impact properties of Cr-Mo-V die steel was studied by means of metallographic microscope, scanning electron microscope, high resolution transmission electron microscope and impact testing machine. The results show that compared with conventional upsetting and drawing deformation, the microstructure and network carbides of the die steel after spheroidizing annealing under secondary radial forging and secondary upsetting and drawing deformation processes are significantly optimized, the impact absorbed energy are improved by 12% and 58%, respectively, and the precipitated carbides increases in quantity and is dispersed.

Key words: die steel, secondary forging deformation, microstructure, impact properties
