Very strong pure Ti, with room temperature compressive yield stresses up to 1.80 GPa, was developed by field assisted hot pressing of a mixture of hcp (α) and fcc powders produced by mechanical milling. During consolidation the fcc phase decomposes into α-Ti and a dispersion of TiC particles. Tuning the pressing temperature and time allows controlling the grain and particle size and, thus, the yield strength and plasticity. © 2014 Elsevier B.V.
