Speckle Pattern of the Surface Layer of Titanium Alloy GRADE 2 and Steel 3723HR Samples under Deformation

Abstract:

The deformation behavior during tension of titanium GRADE 2 and steel 3723HR samples is investigated. The distribution of localized plasticity foci in the near-surface layers of samples of two materials is studied. A correlation between the stages on deformation curves and evolution patterns of spatial localized plasticity foci on titanium alloy GRADE 2 and steel 3723HR is established. It is established that a different type of deformation diagrams σ=f (ε)) during tension of metallic materials is manifested in the different distribution character of deformation fields at different stages of the deformation curve.
