Influence of Carburization on Mechanical Behaviors of NiTiCu Alloy under Dynamic Impact Loading

Abstract:

The mechanical behaviors of bare and carburized NiTiCu specimens under dynamic impact loading were investigated using a home-built impact testing system. The contact force was measured with piezoelectric force sensor and digital signal processing system in real time during impact process. Predicted instantaneous velocity and displacement formula were presented. The results show that the maximum deformation depth of carburized specimens was less than that of bare specimens, and the carburization process can increase absorbed energy and cushion effect to impact of specimens during impact process. The decrease of deformation depth and increase of absorbed energy can reduce the contact force and materials damage of specimens during impact process.
