Definitions

  • FIG. 3 is a schematic diagram illustrating the phases of the TiAl-based intermetallic sintered compact according to the first embodiment.
  • the TiAl phase in the TiAl-based sintered powder particle F 1 is referred to as TiAl phase F 2 and the additional metal phase (Ni phase) is referred to as additional metal phase F 3 .
  • the Ni phase (additional metal phase F 3 ) is present between adjacent TiAl-based sintered powder particles F 1 (grain boundary), that is, between the TiAl phase F 2 of one TiAl-based sintered powder particle F 1 and the TiAl phase F 2 of the adjacent TiAl-based sintered powder particle F 1 .
  • the Ni phase (additional metal phase F 3 ) is present on the periphery of each of a plurality of TiAl-based intermetallic compounds (TiAl phase F 2 ).
  • the TiAl-based intermetallic sintered compact Fx according to Comparative Example 1 contains neither Fe nor Ni. More specifically, the TiAl-based intermetallic sintered compact Fx according to Comparative Example 1 has a Fe content less than 0.05% by weight and a Ni content less than 0.01% by weight. As illustrated in FIG. 5 , the TiAl-based intermetallic sintered compact Fx according to Comparative Example 2 has a Fe content of less than 0.05% by weight and a Ni content of 1.05% by weight. As illustrated in FIG. 5 , the TiAl-based intermetallic sintered compact F according to Example 1 contains Ni alone as an additional metal, in which the Ni content is 0.2% by weight of the total content, and the Fe content is less than 0.05% by weight of the total content.
  • FIG. 10 is a plot of results of Comparative Examples 1 and 2 and Examples 1 and 2. As illustrated in FIG. 10 , when the TiAl-based intermetallic sintered compact F containing Ni alone as an additional metal has a Ni content of 0.1% by weight to 1% by weight of the total content, the sintered density is high and occurrence of a ⁇ -phase colony is suppressed.
