The MgB₂-based samples were synthesized at 2 GPa at 800 and 1050 °C for 1 hour with and without Ti and SiC. X-ray, SEM and Auger structural studies showed that with increasing of manufacturing temperature grain boundary pinning transforms into point pinning, which is well correlated with the transfo...
