The effect of ageing on resistivity, thermoelectromotive power vs Pt and specific heat of the Ni-14.5Cr-1.5Si(wt%) alloy was studied. After quenching, this alloy experiences a transformation from disorder to short range order. Results showed that the resistivity inereased signifitantly by ageing, but the thermoelectromotive power and specific heat increased only slightly. X-ray diffraction analysis showed that this is caused by the formation of the δ-second phase, which is a Ni2Si compound.
