Characterisation of Uranium-3/4% Titanium Alloys Extruded from the Gamma Phase.

Abstract

The effects of quench rate, mode of quenching and subsequent ageing treatments on microstructure and properties of a U- wt % Ti alloy have been investigated. Particular emphasis has been placed upon heat treatment of 35mm diameter, gamma-extruded, bar. Cooling rates in the range 2 to 480 K/s were obtained, resulting in a wide spectrum of microstructures ranging from granular alpha after slow rates of cooling to almost fully martensitic alpha after faster cooling. By optimising the rate and mode of quenching the problems of centreline cracking and void formation have been circumvented. Subsequent ageing at 450 C produced hardnesses in excess of 480 Hv30 due to precipitation of U2Ti. (Author)
