Effect of Electromagnetic Stirring on the Microstructure and Mechanical Properties of the High Speed Steel

Abstract:

In order to improve the microstructure and mechanical properties of High Speed Steel (HSS), electromagnetic stirring method is adopted to enhance the solidification of target materials in this paper. The results show that optimization of the microstructure, refinement of the grain, reducing in segregation of the alloy elements, and improvement of the comprehensive properties of HSS can be obtained by the electromagnetic stirring through changing the morphology and distribution of the carbide.
