Effect of Annealing on the Structure and Properties of Titanium Alloy with Cellular Architecture for Medical Applications

摘要

The methods of optical metallography, SEM, x-ray fluorescence analysis, microindentation and compression testing were used to study the effect of annealing of Ti - 6%Al - 4%V alloy produced by direct laser sintering of the powder on structure, phase composition and mechanical properties of the samples with cellular architecture intended for use as bone replacement implants. Annealing of the cellular samples having a relative density of 45% was conducted in the temperature range of 720 - 1000 degrees C for 1 h under high vacuum. Mechanical properties were determined according to ISO 13314 for compression testing of porous metallic materials.
