Titanium alloys are used in many specific applicants such as biomedical, military, sporting goods and aerospace industry due to their high strength properties and low aspect ratio. Even though their outstanding properties, titanium alloys have low utilization rate and relatively low recycling ratio during manufacturing of Titanium parts. In order to determine its mechanical and impact properties for low-cost Ti-based alloy applications, powder size distribution and compacting pressure strongly affect the microstructural properties of the sintered Ti6Al-4V alloy. This paper presents how the narrow particle size distribution affect the impact properties of both recycled and commercially available Ti-6Al-4V alloys. Below 40µm particle size distribution range of Ti-6Al-4V alloys were conducted on 3point bending, Charpy impact test and microstructural evaluation. Results indicate that -40µm size distributed and recycled Ti-6Al-4V alloys show more brittle behaviour than commercial available alloys.
