Strain glass transition in Ni47.5+xTi50−xFe2.5 alloys
Source abstract
Abstract
There have been limited studies on the influence of the Ni/Ti ratio on the strain glass transition behavior in NiTiFe shape memory alloys. In this study, Ni 47.5+xTi 50−xFe 2.5 (x = 0, 0.5, 1.0) alloys were prepared and their microstructural evolution, dynamic mechanical properties, and temperature-dependent electrical resistivity were investigated. We find that increasing Ni/Ti ratio in Ni 48.5Ti 49Fe 2.5 alloy could suppress the long-range martensitic transformation, resulting in the occurrence of strain glass transition characterized by the continuous formation and growth of nanodomains. As a result, a successive softening in elastic modulus and the negative temperature coefficient of electrical resistivity in a broad temperature range have been observed.
