Abstract

The effect of laser power and powder flow rate on properties of laser metal deposited titanium alloy-Ti6Al4V was studied. The laser power was varied between 1.8 kW and 3.0 kW and the powder flow rate was varied between 2.88 g/min and 5.67 g/min. The study showed that as the laser power was increased or the powder flow rate was decreased, there was an increase in the production of Widmastätten alpha structure that results in low microhardness, while at a very low laser power or higher powder flow rate, more of martensitic alpha structure are observed that results in high microhardness.
