摘要: Abstract The internal oxidation zone (IOZ) of a Sm(Co bal Fe 0.22 Cu 0.08 Zr 0.02 ) 7.5 alloy formed in air at 700 °C was characterized using transmission electron microscopy (TEM). It shows that the oxides are varied composition and size with depth, from mainly fine FeSmO 3 shallow area to larger Sm 2 O deeper area. also causes formation thin phase transformation between IOZ alloy. mechanism, together oxidation-induced magnetic matrix phases alloy, is fully disclosed.
