Abstract Scope |
This talk will discuss the effects of rapid solidification on the solidification microstructures in multiple β and near-β Ti alloys produced via two piston splat quenching (SQ). Three Ti-Mo binary alloys, Ti5.4wt%Mo, Ti9.6wt%Mo, and Ti12wt%Mo, were produced through arc melting. These alloys and Ti-5553 were rapidly solidified using SQ. Combustion analysis was used to ascertain the concentration of interstitial elements (oxygen and nitrogen) absorbed during the alloy feedstock development and SQ processes. Electron microscopy and x-ray microanalysis are being employed at micro- and nanoscales to characterize splat features including phase composition, grain structure, and chemical homogeneity. The presence of possible secondary phases in these alloys will be correlated with the uptake of interstitial gases and segregation of molybdenum upon rapid solidification.
