Microstructure and mechanical properties of Ti–Re alloys manufactured by selective laser melting
Abstract
In the present study, a commercially pure (CP) Ti and Ti–Re alloys containing 2 and 4 wt% of Re were manufacturedby selective laser melting (SLM) and characterized in terms of microstructure, strength and fatiguecrack propagation resistance. On the contrary to a homogenous lath-type martensitic α′ microstructure with nosigns of directional solidification observed for CP Ti, the Re addition led to development of columnar prior βgrains oriented along building direction with a much finer acicular α′ martensite in Ti–Re alloys. The width ofmartensitic α′ needles decreased with increasing Re content. Re affected also the formation of different phaseconstituents. The presence of ω phase precipitates as well as residual undissolved Re particles was noticed inTi–Re alloys. Ti–Re alloys exhibited also the substantially increased ultimate tensile strength and drasticallyreduced ductility in comparison to CP Ti. These findings have been discussed in the paper considering the highlyrefined acicular α′ martensitic structure, the increased oxygen content as well as the presence of strengthening ωphase precipitates in Ti–Re alloys. Finally, the brittleness of Ti–Re alloys caused the deterioration of their fatiguecrack propagation resistance.
