オーステナイトステンレス鋼の鏡面について

抄録

A mirror surface of austenitic stainless steel was finished by polishing with an aqueous suspension of alumina. During the colloid chemical polishing, the oxide particles were evenly embedded in the substrate, and at the same time the surface layer underwent a martesitic transformation.
The solid state reaction that took place between the abrasive oxide particles and the alloy substrate was promoted in virtue of the magneto-catalytic Hedvall effect, since the martensitic transformation concerned gave rise to a ferromagnetic and distorted lattice structure.
The lustrous mirror surface that was obtained proved to be dielectric, ferromagnetic and corrosionresistant so that it was susceptible to the electrooptic effect, e. g. to Faraday and Kerr effect.
The crystallographic, magnetic, and dielectric analyses were carried out in terms of electron diffraction reflection, and it was demonstrated that this procedure could serve as a quality testing of austenitic steel.
