A novel technique for introducing pulsed magnetic field (PMF) during isothermal holding period of A356 Al alloy has been employed to prepare semisolid slurry. The effects of vibration frequency of PMF on morphology of the primary phase in semisolid A356 Al alloy slurry were studied, and some characteristic parameters characterized the morphology and grain size of the primary phase were obtained. The...
EPR and magnetic susceptibility measurements have been performed on xFe 2 O 3 1.5Sb 2 O 3 (1-x)TeO 2 glasses with 11 ≤ x ≤ 15 mol%. The data give evidence that the iron ions in these glasses are in Fe 3+ and Fe 2+ valence states, which explains their magnetic behaviour.
