The research of compression and energy absorption property of Ti6A14V porous structure based on selective laser melting

摘要

Ti6Al4V porous structure was fabricated by selective laser melting. Through the compression experiment, compression strength and energy absorption characteristics of Ti6Al4V porous structure with different rod diameters were studied. The results show that stress - strain curve of the porous structure of Ti6Al4V is divided into three stages: elastic stage, platform stage and close-grained crushing stage. The compression performance and energy absorption capacity of porous structure dramatically climbed with the increase of the rod diameter.
