Some aspects of thermally induced martensite in Fe-30% Ni-5% Cu alloy

Abstract

Kinetical, morphological, crystallographical and several thermal properties of thermally induced martensite in the austenite phase ofFe–30% Ni–5% Cu alloy were investigated. Scanning electron microscope (SEM), transmission electron microscope (TEM) anddifferential scanning calorimetry (DSC) techniques were used during study. Kinetics of the transformation was found to be as athermaltype. SEM and TEM observations revealeda0(BCC) martensite formation in the austenite phase of alloy by thermal effect. Thesethermally induceda0martensites exhibited a thin plate-like morphology with twinnings.r2007 Elsevier B.V. All rights reserved.
