Abstract
The microstructures of Ticonal G and Ticonal X in the condition of optimum magnetic properties are studied by the electron microscope using the direct carbon replica. It is argued that a very critical and extensive checking of results is essential in order to arrive at reliable conclusions. Work along these lines demonstrates that: (a) The main structural patterns for Ticonal G and X are the same; (b) the details of the structure of Ticonal G and X differ strikingly with respect to texture, width, length‐to‐width ratio, delineation and intergrowth; and (c) the influence of the magnetic field during cooling on the structure of Ticonal G on a plane ∥Hu can be shown directly. It cannot yet be decided whether the structure in the optimum condition is a true two‐phase structure or a single‐phase structure with periodic fluctuations in composition. It is possible that the dimensions revealed by etching do not represent those of the magnetic areas.This publication has 1 reference indexed in Scilit:
