The Physical Properties of V(Fe,Co,Ni)3 Alloys from 300 to 1000 K
The temperature dependence of the transport properties [thermal conductivity (λ), electrical resistivity (ρ), and thermopower (S)] and the thermal expansion coefficients [differential (αo) and mean αm)] were determined in the range 300 to 1000 K for three alloys: water quenched V(Fe0. 22Co0.78)3, ordered V(Fe0.22Co0.78)3 and ordered V(Fe0.6Ni0.4)3, modified with Ti. These long-range-ordered alloys have superior structural performance at elevated temperatures1–4 and one goal of this study was to determine the ratio, α0/λ, which is needed to assess the resistance of these experimental alloys to thermal stresses in advanced power system applications.
