Özet

Kinetical, morphological, crystallographical and several thermal properties of thermally induced martensite in the austenite phase of Fe-30% Ni-5% Cu alloy were investigated. Scanning electron microscope (SEM), transmission electron microscope (TEM) and differential scanning calorimetry (DSC) techniques were used during study. Kinetics of the transformation was found to be as athermal type. SEM and TEM observations revealed α′ (BCC) martensite formation in the austenite phase of alloy by thermal effect. These thermally induced α′ martensites exhibited a thin plate-like morphology with twinnings. © 2007 Elsevier B.V. All rights reserved.
