Abstract
The strengthening of titanium and beta III alloy by dispersions of ceria, yttria and misch metal oxides is investigated. The oxides were incorporated in the matrix by internal oxidation. The warm-rolled strips of these materials were annealed at high temperatures. The recovery of the mechanical properties and microstructure were followed by hardness and tensile testing and by optical and electron microscopy. These studies revealed that whilst the dispersoids do not prevent recrystallization, they hinder grain growth. High temperature tensile tests indicate that increase in strength brought about by dispersoids is temperature dependent and falls off above 600°C.
