Effect of nano-yttria stabilized zirconia addition on the microstructure and mechanical properties of Ti6Al4V parts manufactured by selective laser melting

This study presents the results of selective laser melting (SLM) of Ti6Al4V reinforced with 1% and 2.5% (wt%) nano yttria-stabilized zirconia (nYSZ). The bulk parts showed a very high building density which means that the melting parameters were optimal. X-ray diffraction analysis confirmed the existence of a near-alpha microstructure. No change in grains shape was noticed after the addition of nYSZ, columnar and lamellar grains remained...
