Abstract
Aging regime, below and at room temperature, of the martensite formed in an Fe-24.67Ni-0.87C (mass pct) alloy (M s = 160 K) is studied by using a poly crystalline X-ray diffraction technique. Parameters such as tetragonal axial ratio, unit cell volume, intensity ratios of the tetragonal doublet peaks,etc. are obtained for various degrees of aging. At temperature below ∼200 K, where the carbon atoms can shift only into their neighboring sites, the variation of the parameters indicates some discrepancies with the existing models. At room temperature, a new peak appears in between the tetragonal doublet peaks. This peak and the variation of the parameters at room temperature are explained in terms of carbon cluster formation.
