Sintering of Titanium Alloyed Steels

AbstractAn investigation into the manufacture of sintered steels containing titanium as an alloying element is reported. Transient liquid phase sintering has been used. Titanium may be used to generate three types of alloy system: (i) microalloyed, (ii) solid solution strengthened, and (iii) precipitation hardened. Structural alterations and shrinkage during sintering, as well as mechanical properties developed following heat treatment, are presented and discussed. Ultimate tensile strength and elongation to failure were found to be ∼500 MN m−2 and 5%, 400–450MN m −2 and 25–20%, and 600–700 MN m−2 and 3–2% for alloys of types (i), (ii), and (iii), respectively.
