{sup 57}Fe Moessbauer spectra of YTi(Fe{sub 1{minus}{ital x}}M{sub {ital x}}){sub 11} (M=Co and Ni) have been studied. The average isomer shifts increase monotonically. The average quadrupole splittings have a sudden change for YTi(Fe{sub 1{minus}{ital x}}Co{sub {ital x}}){sub 11} between {ital x}=0.4 and 0.6. It appears that a spin reorientation occurs over this composition range. Both hyperfine fields for the three sites and the average field increase at first, and then decrease with increasing Co or Ni concentration. The maximum of the average hyperfine field is 27.7 T at {ital x}=0.6 for YTi(Fe{sub 1{minus}{ital x}}Co{sub {ital x}}){sub 11} and 24.1 T at about {ital x}=0.2 for YTi(Fe{sub 1{minus}{ital x}}Ni{sub {ital x}}){sub 11}. The average moments of Co and Ni atoms are 1.3(1){mu}{sub {ital B}} and 0.6(1){mu}{sub {ital B}}, respectively, obtained from the formula {mu} = (1 {minus} {ital x}){mu}{sub Fe} + {ital x}{mu}{sub {ital T}}.
