Long fatigue crack growth in Ti6Al4V produced by direct metal laser sintering
Original language description
Results of an experimental determination of the propagation of long fatigue cracks in Ti6Al4V alloy prepared bynselective laser melting technology are presented. Direct metal laser sintering (DMLS) exploiting EOSINT M270nsystem was used for fabrication of compact tension specimens having different orientation in relation to the buildndirection.nIt has been found that there is no substantial influence of the build orientation and thus the microstructure exhibitingndirectionality on the growth of long fatigue cracks and on the crack propagation threshold, when optimal processnparameters and subsequent stress relieving heat treatments at 380 °C for 8 hours are chosen.nThe results were compared with literature data on the growth of long cracks in Ti6Al4V alloy manufactured bynDMLS technique and with data for conventionally produced forged material.nThe fatigue crack propagation path, fracture surfaces and fracture surface roughness were investigated. An analysisnof the specific microstructure produced by the direct laser sintering was performed and discussed in terms of thenmechanism of the propagation of long cracks.
