Description
Summary:Mechanical alloying was used to synthesize Nb3Al superconductor successfully, and the process was optimization under various preparation conditions. In the current study, Nb3Al superconductor with Tc of 15.6 K was directly prepared from high quality Nb (Al) solid solution by mechanical alloying method and heat treatment at a low temperature of 800 to 900 °C. The results showed that Nb3Al superconducting wire with high performance could be prepared after heat treatment below the melting point of Cu (1080°C) and using Nb (Al) solid solution and conventional powder in tube (PIT) method, thus effectively avoiding ultra-high temperature heat treatment and special rapid heating and quenching (RHQ) device.
