The composite material showed homogeneous distribution of MgB2 particles in the Al-matrix with neither any aggregation of particles nor defects such as cracks oř cavities. The critical temperature of superconducting transition (Tc) was determined by electrical resistivity and magnetization to be about 37-39K. A billet of the superconducting composite materiál was successfully hot-extruded, forming a rod of 10 mm and wires of 3 and l mm in diameter. These intermediate products showed the onset Tc of electrical resistivity also at 37-39 K. Microstructures of these samples have been observed by TEM and SEM method to establish morphology and crystallography of particles. The magnetooptic (MO) imaging method has been applied to measure magnetic flux through this material when in external field.
