Abstract
AbstractThis paper presents a detailed investigation of a complex cellular transformation in an Fe-25Ni-20Cr-2Al-2Ti alloy. Convergent beam electron diffraction and energy dispersive X-ray spectroscopy are used to monitor the reaction, including the precipitation on existing grain boundaries which precedes the cellular transformation. It is shown that growth of this cellular precipitation involves the volume diffusion of solute such that the growth rate decreases with aging time. The consequences of this decrease of reaction rate are discussed with particular reference to the types of cellular transformation product formed.
