| Abstract Scope |
To evaluate relation between mechanical properties and structure of Ti-6Al-4V ELI alloy (Ti64; ASTM grade23) fabricated using additive manufacturing (AM) for biomedical applications.
AM dumbbell- shaped and disc specimens of Ti64 were built on AM-machine with a laser beam. Cast-specimens were used as controls. Tensile properties were conducted at a crosshead speed of 0.25 mm/min (n=4). Electron back scatter diffractions (EBSD) were performed using a scanning electron scope. Phase and texture were obtained from the mirror surface of as-fabricated materials (n=1). The data was analyzed using Student t-test (α=0.05).
The strength of the AM-specimens was higher than that of cast-specimens (p<0.05). The grain size and α/β lamellar of AM-Ti64 tended to be finer than that of cast-Ti64 due to the relatively rapid cooling rate. Kernel Average Misorientation of the AM-Ti64 was smaller than that of cast-Ti64. From these findings, AM-Ti64 should be a very useful fabrication method for biocompatible applications. |
