Microstructure and Magnetic Properties of Cobalt-Chromium Alloys

摘要

Microstructural details and magnetic properties of Co-Cr in the thin film form are being extensively investigated. It is also worthwhile to consider Co-Cr as a metallurgical system. Objectives of this study were to investigate: the microstructural evolution of these alloys as function of Cr content; the magnetic properties of these alloys as function of Cr content and to extend this understanding to elucidate the microstructure/property correlations. It was found that Cr additions enhanced the fcc phase retention and subsequently the fault density. The additions also decreased saturation magnetization and grain size. Furthermore, the intrinsic coercivity was fairly insensitive to Cr additions for a given grain size and the coercivity increased with decreasing grain size. 35 refs., 36 figs., 2 tabs.
