Механические свойства поверхностных Ti-Ni-Ta- и Ti-Ni-Ta-Si-сплавов, синтезированных на подложках из никелида титана

The physical-mechanical properties of Ti-Ni-Ta and Ti-Ni-Ta-Si-based surface alloys ~1 μm thickness synthesized on the NiTi substrates by additive thin-film electron beam method were investigated. effect these functional composite systems [Ti-Ni-Ta alloy/TiNi substrate] [Ti-Ni-Ta-Si was explored. It established that Ti-Ni-Ta-Si based alloy with an amorphous structure is characterized higher gradients hardness Young’s modulus in comparison alloy, has increased ~10% ~2 times greater plasticity compared to initial substrate respectively. Evaluation shape memory superelasticity shown synthesis results almost 2-fold increase martensitic shear stress a significant decrease hysteresis width untreated TiNi samples.
