Abstract
We demonstrate a powder metallurgy synthesis route for porous Ti–6Al–4V structures by consolidation of Ti–6Al–4V alloy powders and describe the influence of the processing conditions. Ti–6Al–4V foams with 50 vol% porosity having high strength were fabricated by low temperature solid state deformation at temperatures below 873 K. The open cellular structure consists of continuously connected Ti–6Al–4V struts and homogeneously distributed pores with nominal diameters between 10 and 50 µm and 150–500 µm length.
