| Abstract: | The vacuum melting and argon protecting continuous unidirectional solidification technology was introduced, which combines vacuum inductive melting with continuous unidirectional solidification. Integrating melting, purification and solidification, the system has convenient control, strong ability to mix and oxidize and higher efficiency, and can produce pure and high-class materials with unidirectional microstructure. A Cu bar of 8 m in length with columned crystals, was made with self-made equipment based on the technology and its microstructure and properties were analyzed. |
