Abstract
The mechanical properties of sintered titanium were examined in relation to the oxygen content, and the sintering process using calcium as the getter of oxygen was investigated.
The results obtained are summarized as follows:
(1) The elongation of titanium sintered in vacuum by the conventional method was much lower than that of vacuum-melted titanium containing about the same amount of oxygen.
(2) The ductility of sintered titanium was considerably improved by using calcium as the getter of oxygen.
(3) The mechanical properties of sintered titanium were affected not only by the total amount of oxygen content, but also by the oxygen gathering around the pores during sintering.
