Comparison of deformation behavior of 316L stainless steel and Ti6Al4V alloy applied in traumatology

Abstract

The comparative analysis of mechanical properties was performed for AISI 316L stainless steel and Ti6Al4V alloy using the digital image correlation (DIC) method. Both types of materials are commonly used for implants in traumatology. Tensile tests of the cylindrical tensile specimens were performed at room temperature and at an initial strain rate of 0,0025 s-1. The strain analysis during tensile tests was carried out by means of Vic 2D image correlation software. Ti6Al4V alloy showed higher yield strength and tensile strength. The differences in the strain localization zones were observed.
