Detection of the structure of sintered materials of the Me-MeO system by ionic bombardment

Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Summary

  1. 1.

    Detection of the structure of deformed SAP by the ionic etching method has shown the considerable practical value of the method, surpassing in its possibilities the previously used methods of chemical etching, electroetching and others. The ionic etching method may be recommended for the preparation of specimens for examination in the electron microscope.

  2. 2.

    Analysis of the microstructure of deformed SAP showed that the base of the material is a cellular network of oxide particles, forming the boundaries of the aluminum pseudograins. A large number of small oxide particles are contained in such pseudograins. In the deformation process, the grains are elongated, giving rise to a deformation texture.

  3. 3.

    The presence in the original material of particles of different sizes results in a structure possessing a large number of aluminum layers of uneven size, leading to a considerable scatter in mechanical properties.
