摘要：

Titanium is characterised by two contrasting aspects: outstanding combination of properties and high production costs which confine its application to high demanding sectors. The employment of powder metallurgy (P/M) techniques is one creative alternative to lower the final costs of titanium products due to some intrinsic advantages of P/M such as high yield of material and limited machining requirement. In this work the performances of hydride-dehydride (HDH) and sponge elemental titanium products obtained by cold uniaxial pressing and sintering are compared. It is found that the two materials achieved similar relative density values but HDH shows much better mechanical performances. (C) 2014 Elsevier Ltd. All rights reserved.
