The Martensitic Transformation in Indium-Thallium Alloys

Conference paper
Part of the The Minerals, Metals & Materials Series book series (MMMS)

Abstract

The martensitic transformation in indium-thallium alloys is reviewed with a focus on the nature of the transformation as has been investigated using elastic and lattice vibrational properties. Recent measurements from thermal-neutron Laue and cold-neutron, triple-axis experiments are presented in an attempt to ratify the traditional explanation for the transformation as being driven by phonon softening for low-ζ \( \left[ {\upzeta \upzeta 0} \right]\left[ {{\upzeta{{ \bar{\upzeta }}}}0} \right] \) (i.e., T1) phonons. No evidence for phonon softening has been found to as low as ζ = 0.02 reciprocal lattice units on the T1 phonon branch. An alternative mechanism is advanced, for the transformation involving nucleation and growth on {111} planes, which appears to be consistent with electron diffuse scattering in the system. Such a mechanism is also consistent with the transition being driven by the electronic free energy of the system, as has been demonstrated by other properties.
