TEM examination proves that the second phase particle within the as-forged Ti-55alloy consists of either bright or dark "matrix" (nano-Nd3Sn) and some small dark blocks (SnO) dispersed in the "matrix". The HREM observation shows that the nanoNd3Sn phase is roughly spherical and about 3-15nm in diameter, and the grain boundaries with atout 1nm width are "gas-like" structure.
