Abstract

Extremely fine coherent precipitates of ordered Ti3Al and relatively coarse incoherent precipitates of S2 suicide exist together in the near α-titanium alloy, Timetal 834, in the dual phase matrix of primary α and transformed β. In order to assess the role of these precipitates, three heat treatments viz. WQ, WQ-A and WQ-OA, were given to have no precipitates, Ti3Al and suicide and only suicide precipitates in the respective conditions. Tensile properties in the above three heat treated conditions were determined at room temperature, 673 K and 873 K. It was observed that largely Ti3Al precipitates were responsible for increase in the yield strength and decrease in ductility in this alloy. © Indian Academy of Sciences.
