Conclusions

  1. 1.

    It was established that in the alloys Ti0.5Ni0.5-xFex, as the Fe concentration increases, a correlated decrease occurs in the temperature of martensitic transformations and premartensitic anomalies of the shear modulus and electrical resistance down to complete disappearance of these anomalies and structural transitions x≥0.25.

  2. 2.

    A diagram of the martensitic transformations of the system Ti0.5−xNi0.5−xFex was constructed. E was established that, in general, the starting structure undergoes a chain of martensitic transformations: B2 → R(Ω)→R(Ω)+B19′′ B19′→B19″.

  3. 3.

    The concentration dependence of the lattice parameters of the starting phase was observed to deviate from linearity for low Fe concentrations and it is precisely in this range of concentrations that martensite transformations and premartensite anomalies in the properties of the alloys are observed.
