Effect of Heat Treatment on Compressive Behavior of Selectively Laser Melted Ti64 Scaffolds

摘要

Abstract Ti-based alloys have recently been developed for a variety of applications. Because of its unique properties like excellent elasticity, shape memory, low Young's modulus, bio-corrosion resistance, good biocompatibility, and bio-implant applications have received a lot of interest. However, because dense Ti alloys have greater mechanical strength and elastic modulus, porous structures were employed instead of dense Ti alloys to get similar results to human bones. Extensive research has been performed to develop porous Ti alloy scaffolds of low elastic modulus and good strength for the replacement of human bone by changing porosity and input parameters. This work primarily focuses on the compressive behavior of porous titanium scaffolds which is influenced by heat treatment. The compressive test of fabricated porous Ti scaffolds was carried out by INSTRON machine and models were analyzed using FE simulation (ANSYS 2020 R2) with a load of?±?25?kN distributed uniformly and the result shows good potential for biomedical application as bone implants.
