Abstract

Abstract: Mechanical spectroscopy methods and X-ray analysis were used to study the effect of aging in the gap of the spinodal decomposition on the structure and properties (shape memory effect) of the Mn-Cu alloys. It is shown that martensitic transformation and shape memory effect in the Mn40Cu60 alloy has been made possible due to spinodal decomposition of γ-solid solution at aging, so the left boundary of the spinodal decomposition extends to a concentration of 40 at. % Mn.
