Mechanical Properties of NixTi1-x Alloy for Medical Application

Abstract

The effect of Ni:Ti ratios in Ni_xTi_x-1 shape memory alloy at x equal to 0.9, 0.8, 0.7, 0.6, and 0.5 wt% prepared using the solid-state reaction method for medical applications have been studied. The mechanical properties of the alloy included hardness, impact, and Young's modulus which play an important role of issues were examined. The hardness values of 590.16, 670.41, 735.15, 888.03, and 901.17, which correspond to ratios of 90:10, 80:20, 70:30, 60:40 and 50:50 respectively. Besides the impact test recorded the highest value of 9.12 (KJ/m²) at the ratio of 50:50, and the lowest value of 5.32 (KJ/m²) for the 90:10 ratio. The Young's modulus of nickel-titanium (Ni-Ti) alloy have the highest value at a 50:50 ratio of nickel to titanium which considered as the optimal ratio depend on all there tested. The reason is that the ideal balance between nickel and titanium in the alloy provides maximum hardness and flexibility, making it particularly suitable for applications that require strong and stable mechanical properties, such as medical applications, which is useful in medical applications compared to other ratios.
