Hot extrusion of Be–Ti powder

•Extrusion in double-walled containment of Be–Ti blended powder was investigated.•Fabrication of Be–Ti rods by extrusion at 700°C showed more satisfactory results compared to an extrusion at 900°C.•Factors which influence homogeneous and stable metal flow during extrusion are discussed. Be–30.8wt.%Ti powder mixture was extruded in copper and steel containers at 700 and 900°C, respectively. In both cases, achieved extrusion ratio was 7:1. Investigations of microstructure of manufactured Be–Ti rods revealed that processing temperature has a great influence on the metal flow during the extrusion as well as formation of beryllide phases. The results obtained by X-ray diffraction (XRD) analysis proved that brittle intermetallic phases were formed by processing at 900°C; while no evidence of reaction between beryllium and titanium was detected after extrusion at 700°C. Additionally, high-temperature annealing tests of produced Be–Ti samples were performed in order to study the evolution of the phase composition after the heat treatment. The effects of different mechanical properties of core materials (beryllium and titanium) and containers on uniform deformation are discussed in this work.
