Evolution of Structural-Phase States in TiNi Surface Layers Synthesized by Electron Beam Treatment

Figure 5

Lattice parameter a_B2 versus sin²𝜓 in the TiNi specimens after irradiation with 20 pulses at 𝐸₁=4 J/cm²: 𝛼=1^∘ (1), 𝛼=3^∘ (2) and 𝛼=10^∘ (3); 𝑎₀ is the lattice parameter of the B2 phase in the initial specimen.
