TI-FE ALLOY COMPRISING BI OR PB IN COLONY BOUNDARIES

摘要

The present invention provides Ti-Fe alloys. The alloys are provided with a Ti-Fe structure having colonies with Pb or Bi contained within the colony boundaries. The colonies can have a lamellar structure with an alternating arrangement of a β-Ti phase and a TiFe phase or an eutectic structure. In such alloys, the Pb or Bi of 0.3 to 1 in an atomic number can be contained when a total atomic number for the Ti and the Fe is made to be 100. More specifically, the alloys can have a composition of (Ti70.5Fe29.5)100-x(Y)x (Y is Pb or Bi, 0.3<=x<=1).
