Effects of pinning and atomic ordering on damping properties and martensitic transformation of copper-based shape memory alloys

摘要

The effects of long-range atomic order and pinning of interfaces on anelastic properties of Cu-based martensite have been distinguished by means of studying strain amplitude dependences of internal friction and Young's modulus defect, assuming that low- and high-amplitude stages of the strain amplitude dependence correspond to the oscillations within and beyond pinning atmospheres.
