Inelasticity of a Porous Ti–18Zr–15Nb Powder Alloy

Galina Viktorovna Markova, Darya Permyakova, A. D. Gusev

Abstract The temperature spectra of internal friction and the resonance frequency of a Ti–18Zr–15Nb powder alloy with different porosity levels have been studied. The inelastic and elastic effects of different natures have been identified. In the samples with porosity exceeding 50%, an …

Modeling of the effect of porosity on the Young’s modulus of titanium powder alloys

Vladimir M. Volgin, Darya Permyakova, Galina Viktorovna Markova

Titanium powder alloys with superelasticity, corrosion resistance, and good biochemical and biomechanical compatibility have good prospects for use as materials for bone implants. The porous structure of such alloys has a great influence on their elastic characteristics — with increasing porosity, the …

Torsional behavior of Ni-rich NiTi alloys obtained by powder metallurgy and hot deformation

Sergey Volodko, Galina Markova, S. N. Yudin, Darya Permyakova et autres

The effects of severe plastic deformation on NiTi alloys' structure and properties have been extensively studied over the past decades. However, there is a notable lack of systematic data regarding the impact of industrial hot deformation techniques on these alloys. This gap …
