Continuous compression behaviors of selective laser melting Ti-6Al-4V alloy with cuboctahedron cellular structures
Cellular structures often show fluctuating stresses in compression stress-strain curves. Such fluctuating stresses correspond to strut fractures. In this study, the cellular Ti-6Al-4V alloy with cuboctahedron structure was prepared by selective laser melting. The cuboctahedron cellular structures sh...

| description | Cellular structures often show fluctuating stresses in compression stress-strain curves. Such fluctuating stresses correspond to strut fractures. In this study, the cellular Ti-6Al-4V alloy with cuboctahedron structure was prepared by selective laser melting. The cuboctahedron cellular structures showed reduced fluctuations in their compressive stress-strain curves after the initial yielding peak. Their moduli were modulated via the porosity of the structure by changing the strut diameter. A compressive modulus of between 1.3 and 4.868 GPa can be achieved by varying the porosity in the cellular structures between 33% and 84%. Both heat treatment and hot isostatic press (HIP) treatment reduced the fracture strength of the struts during compression due to the conversion of the α′ martensite phase into the more ductile α + β phase. The cellular structure with HIP treatment produced a continuous stress-strain curve during compression, indicating uniform strain distribution behavior. The continuous compressive stress-strain curve can lead to reduced debris formation during compression processes. The deformation showed either bending or stretching mechanisms depending on whether the supports were included along the building direction. The design concepts of cellular structures demonstrated in this study will be valuable in future biomedical applications.
•Continuous compression behaviors of SLM Ti-6Al-4V alloy are shown.•New cuboctahedron strut design reduces layer-wise failure.•Both oblique and in-horizontal-plan struts are needed to distribute applied load.•HIP treatment improves ductility and leads to continuous stress-strain curves.•New design reduces inflammatory response when the implants suffer unexpected force. |
