摘要：
The paper presents a new containerless technique for metallic materials processing based on the simultaneous application of a high frequency electromagnetic field and an inhomogeneous DC magnetic field of strong intensity. It is shown how the superposition of the DC magnetic field strongly enhances the stability of the electromagnetic levitation. Levitation experiments on massive paramagnetic samples involving the combined magnetic and electromagnetic fields are described and analyzed. Conditions to solidify pure Ti and Ti-Al alloys samples of 45 g without contact are presented.
