As-cast microstructure characteristics dependent on solidification mode in TiAl-Nb alloys

Journal of Alloys and Compounds, 2019
Abstract In this work, as-cast microstructure characteristics are identified for the TiAl–Nb alloys with four typical solidification modes, namely, single β (B mode), hypo-peritectic (BA mode), hyper-peritectic (BAA mode) and single α (A mode) solidification. B mode alloys are chemically more homogeneous, and they show netty white ridge β-segregation

Grain refinement by trace TiB2 addition in conventional cast TiAl-based alloy

Materials Characterization, 2015
Abstract Effects of trace TiB2 addition on the solidification microstructure of Ti–48Al–2Cr–2Nb + (0.18, 0.54, 0.9) wt.% TiB2 alloys were investigated by arc melting and electromagnetic levitation melting in this paper. Results showed that the matrix alloy generated a large-grained (~ 800 μm) fully lamellar microstructure, and the grain size ...

TEM investigation on the interfacial boundaries in as-cast Ti3Al+TiAl alloy

Acta Metallurgica et Materialia, 1991
Abstract Ti3Al/TiAl interfaces and TiAl/TiAlT thermal twin boundaries were investigated by transmission electron microscopy in a Ti-42 at.%Al as-cast and homogenized alloy. Intrinsic and extrinsic interfacial dislocations (IIDs and EIDs respectively) have been found on the Ti3Al/TiAl interfaces.
