Ti-6 Al-4 V alloys containing discontinuous TiB precipitates are expected to have desirable combinations of specific strength, stiffness and fracture toughness. One of the key issues in processing these alloys is to develop methods that will allow control of microstructure to achieve the desired properties. Successful commercialization of these alloys also demands that the processing approach be affordable. Melt processing is a promising route to achieve microstructural control and process affordability. This talk will report on the current state of a melt processing approach for producing Ti-6 Al-4 V alloys with B additions. Target compositions have included both eutectic and hypereutectic compositions. In addition, the effect of varying the boron source, i.e., B versus TiB sub 2, was also studied. The role of process variables such as cooling rate, boron content, starting boron source, etc., on the resulting microstructure will be discussed. Insights into microstructural control will be discussed, and relevant implications for achieving desirable mechanical behavior and affordable manufacturing will be drawn.
