| 1 | Manufacturing size effect on the structural and mechanical properties of additively manufactured Ti-6Al-4V microbeams显示文摘The size effect of Ti-6Al-4V submillimeter structures manufactured by selective laser melting,which is critical for metallic mechanical metamaterials of unique mechanical properties,for example,nega-tive Poisson’s ratio and ultrahigh modulus,which show promise in biomedical,environmental,energy-related applications,has not been systematically investigated.Presented here are the quantification of the porosities by X-ray microtomography scans,texture analysis,and mechanical characterization of the addi-tively manufactured Ti-6Al-4V microbeams.We found linearly decreasing porosities,increasing mechan-ical properties,and increasing texture in the microbeam with increasing diameter from 250 to 500μm.The variation of microstructure in microbeams of different diameters and along the sample height,result-ing from the printing parameters and the thermal conditions,leads to the discrepancy between the be-havior observed in experiments and finite element simulation.Our results provide the structure-property-processing correlation to improve the manufacturing and prediction of the mechanical behavior of metal-lic mechanical metamaterials. | Kaiyang Yin Bo Cao Juraj Todt Florian Gutmann Hasan Furkan Tunçay Antonina Roth Frank Fischer Nadira Grübel Aron Pfaff Georg C.Ganzenmüller Jozef Keckes Stefan Hiermaier Christoph Eberl | 2023 | Journal of Materials Science & Technology2023，，18： | 0 |
