Thermo-mechanical simulation cycles for expecting dynamic recrystallization parameters of high sectional density steel for kinetic energy penetrator

A kinetic energy penetrator (KEP) is a type of ammunition designed to penetrate vehicle armour using a high-sectional density projectiles. KEP does not contain explosive payloads and uses purely kinetic energy to penetrate the target. The current project is dealing with providing the steel with elemental Tungsten. Carbon reaches to 0.3% wt in the steel alloy. Thermo-mechanical simulation trails were extensively used for expecting dynamic recrystallization conditions, where grain refinement can be obtained. Grain refinement is a powerful tool for enhancing both strength and impact properties. The simulation work was carried out in the farm work of a cooperation between CMRDI, Tanta university & Division of Materials Processing- Silesian University of Technology in Poland. The simulation outputs (stress- strain curves) were successfully showed peak stress as a result of dynamic recrystallization happening. Moreover, the tensile test results of the primary specimens showed 2000 MPa strength. The team work of the project is looking for more 500 MPa to be added to the previous 2000 MPa.
