A powder metallurgy method includes the steps of forming a member, such as a work piece or an aerospace component, from a titanium alloy powder. The average size of a carbide phase in the titanium alloy powder is controlled in order to control an average size of a carbide phase in the member. In one example, an amount of carbon within the titanium alloy and size of the carbide phase are selected to provide a desirable balance of good hot workability, resisting formation of an alpha-titanium phase within the member and a desired level of fatigue performance.
